At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.Move the compatibility features into a separate header file.

The previous pcf2127 RTC chip could not read and set the correct time.
When reading the data of internal registers, the read address was the
value of register plus 1. This is because this chip requires the host
to send a stop signal after setting the register address and before
reading the register data.This patch sets the register address using dm_i2c_write and reads
the register data using the original dm_i2c_xfer in order to generate
a stop signal after the register address is set, and fixes the bug of
the original read and write time.Signed-off-by: Biwen Li

This adds a compatible string for m41t82. This ensures that this driver
can be used for m41t82 in DM mode, too (asit was usable for this model in
non-DM mode before).In addition, the HT bit has to be reset during probe, since the m41t82
chip sets it when entering battery standby mode.This patch ensures this driver works on socfpga_socrates.

The "Flamingo" carrier-board for the RK3399-Q7 has a RV3029 populated
and the application will use the off-module RV3029 RTC including the
battery backed SRAM.To support this use case, this commit includes the following changes:
* updates the rv3029 driver to use DM
* implements the read8/write8 operationsThis syncs the implementation with the Linux code (based on 4.17),
porting the trickle-charger support from there (with improvements to
avoid unnecessary EEPROM updates) and adheres to the Linux DTS
binding.Signed-off-by: Philipp Tomsich
