Add basic support for S32V234 SIUL2 pin controller, based on i.MX model.
Definitions of MSCR PADs, which are used for I/O (MSCR < 512), were added.
Definitions of IMCR (input only) PADs (MSCR >= 512), corresponding to
specific peripherals like ENET, I2C, UART or uSDHC are going to be added
along with the drivers which need them.Add configurations for specific S32 SoC selection and pinmuxing driver.

Change PINCTRL_IMX to tristate to support loadable module build.
And i.MX common pinctrl driver should depend on CONFIG_OF to make sure
no build error when i.MX common pinctrl driver is enabled for different
architectures without CONFIG_OF.Also add module author, description and license.

Use function callbacks for SCU related functions in pinctrl-imx.c
in order to support the scenario of PINCTRL_IMX is built in while
PINCTRL_IMX_SCU is built as module, all drivers using SCU pinctrl
driver need to initialize the SCU related function callback, and
no need to check CONFIG_PINCTRL_IMX_SCU anymore, hence stub functions
also can be removed.Signed-off-by: Anson Huang

Pull pin control updates from Linus Walleij:
"This is the bulk of the pin control changes for the v5.9 kernel
series:Core changes:
- The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
macro" was put in an immutable branch and merged into the pinctrl
tree as well. We see these changes also here.- Improved debug output for pins used as GPIO.
New drivers:
- Ocelot Sparx5 SoC driver.
- Intel Emmitsburg SoC subdriver.
- Intel Tiger Lake-H SoC subdriver.
- Qualcomm PM660 SoC subdriver.
- Renesas SH-PFC R8A774E1 subdriver.
Driver improvements:
- Linear improvement and cleanups of the Intel drivers for
Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
things.- Renesas SH-PFC has added support for RPC pins, groups, and
functions to r8a77970 and r8a77980.- The newere Freescale (now NXP) i.MX8 pin controllers have been
modularized. This is driven by the Google Android GKI initiative I
think.- Open drain support for pins on the Qualcomm IPQ4019.
- The Ingenic driver can handle both edges IRQ detection.
- A big slew of documentation fixes all over the place.
- A few irqchip template conversions by yours truly.

…in case of error in 'imx_pinctrl_probe()'"
This reverts commit ba403242615c2c99e27af7984b1650771a2cc2c9.
After commit 26d8cde5260b ("pinctrl: freescale: imx: add shared
input select reg support"). i.MX7D has two iomux controllers
iomuxc and iomuxc-lpsr which share select_input register for
daisy chain settings.
If use 'devm_of_iomap()', when probe the iomuxc-lpsr, will call
devm_request_mem_region() for the region <0x30330000-0x3033ffff>
for the first time. Then, next time when probe the iomuxc, API
devm_platform_ioremap_resource() will also use the API
devm_request_mem_region() for the share region <0x30330000-0x3033ffff>
again, then cause issue, log like below:[ 0.179561] imx7d-pinctrl 302c0000.iomuxc-lpsr: initialized IMX pinctrl driver

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.3 kernel cycle:Core changes:
- Device links can optionally be added between a pin control producer
and its consumers. This will affect how the system power management
is handled: a pin controller will not suspend before all of its
consumers have been suspended.This was necessary for the ST Microelectronics STMFX expander and
need to be tested on other systems as well: it makes sense to make
this default in the long run.Right now it is opt-in per driver.
- Drive strength can be specified in microamps. With decreases in
silicon technology, milliamps isn't granular enough, let's make it
possible to select drive strengths in microamps.Right now the Meson (AMlogic) driver needs this.
New drivers:
- New subdriver for the Tegra 194 SoC.
- New subdriver for the Qualcomm SDM845.
- New subdriver for the Qualcomm SM8150.
- New subdriver for the Freescale i.MX8MN (Freescale is now a product
line of NXP).- New subdriver for Marvell MV98DX1135.
Driver improvements:
- The Bitmain BM1880 driver now supports pin config in addition to
muxing.- The Qualcomm drivers can now reserve some GPIOs as taken aside and
not usable for users. This is used in ACPI systems to take out some
GPIO lines used by the BIOS so that noone else (neither kernel nor
userspace) will play with them by mistake and crash the machine.- A slew of refurbishing around the Aspeed drivers (board management
controllers for servers) in preparation for the new Aspeed AST2600
SoC.- A slew of improvements over the SH PFC drivers as usual.
