ad1ff53218 rtc: pcf2127: remove U-Boot specific compatible string
Now that all in-tree boards have been converted to the compatible
strings from Linux, delete the support for the ad-hoc "pcf2127-rtc" one.

7c67ef3f3f rtc: pcf2127: sync with Linux compatible strings
Allow this driver to be used by boards which inherit their device trees
from Linux. Compatibility is temporarily retained with the old
compatible string which is U-Boot specific, and will be removed after a
few changes.

caa4daa2ae dm: treewide: Rename 'platdata' variables to just 'plat'
We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).

Rename some of the latter variables to end with 'plat' for consistency.

a518dd6336 rtc: pcf2127: provide ->read method
This simply consists of renaming the existing pcf2127_read_reg()
helper to follow the naming of the other
methods (i.e. pcf2127_rtc_<method name>) and changing the type of its
"len" parameter.

b8a42e0fcb rtc: pcf2127: don't add/subtract 1 to tm_mon
As noted in rtc_def.h, the tm_mon field in struct rtc_time is 1-12,
unlike in struct tm where it is 0-11. Currently, running "date" prints
the wrong

Date: 2020-04-01 (Friday)    Time: 13:05:30

and setting the RTC via the date command is also broken.

ef6c26d338 rtc: pcf2127: Fixed bug with rtc settings and getting error time
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.
