Add basic clock data for Socionext's new SoC PXs3.

U-Boot does not support fancy clock tree structures like the Linux
common clock framework. Implement a simple clock tree model at the
driver level. With this, the clock data will be simplified.Signed-off-by: Masahiro Yamada

This SoC is too old. It is difficult to maintain any longer.

Fix warnings reported by sparse:
- ... was not declared. Should it be static?"
- cast to restricted __be32While fixing those, the type conflict of cci500_init() was found.

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree onlyAll drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.Note this involves changing some dead code - the imx_lpi2c.c file.

The initial design of the UniPhier clk driver for U-Boot was not
very nice. Here is a re-work to sync it with Linux's clk and reset
drivers, maximizing the code reuse from Linux's clk data.Signed-off-by: Masahiro Yamada

Move U_BOOT_DRIVER() entry from the data file (clk-uniphier-mio.c)
to the core support file (clk-uniphier-core.c) because I do not want
to repeat the driver boilerplate when I add more clock data.Signed-off-by: Masahiro Yamada

This does not have much impact on behavior, but makes code look more
more like Linux. The use of devm_ioremap() often helps to delete
.remove callbacks entirely.Signed-off-by: Masahiro Yamada

The following changes are made to the clock API:
* The concept of "clocks" and "peripheral clocks" are unified; each clock
provider now implements a single set of clocks. This provides a simpler
conceptual interface to clients, and better aligns with device tree
clock bindings.
* Clocks are now identified with a single "struct clk", rather than
requiring clients to store the clock provider device and clock identity
values separately. For simple clock consumers, this isolates clients
from internal details of the clock API.
* clk.h is split so it only contains the client/consumer API, whereas
clk-uclass.h contains the provider API. This aligns with the recently
added reset and mailbox APIs.
* clk_ops .of_xlate(), .request(), and .free() are added so providers
can customize these operations if needed. This also aligns with the
recently added reset and mailbox APIs.
* clk_disable() is added.
* All users of the current clock APIs are updated.
* Sandbox clock tests are updated to exercise clock lookup via DT, and
clock enable/disable.
* rkclk_get_clk() is removed and replaced with standard APIs.Buildman shows no clock-related errors for any board for which buildman
can download a toolchain.test/py passes for sandbox (which invokes the dm clk test amongst
others).Signed-off-by: Stephen Warren

Currently, fdtdec_get_addr_size() does not support the address
translation, so it cannot handle device trees with non-straight
"ranges" properties. (This would be a problem with DTS for UniPhier
ARMv8 SoCs.)Signed-off-by: Masahiro Yamada
