rtc: rv3029: update to support DM and sync with Linux 4.17
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 operations
This 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.

rtc: Allow use of RTC in SPL and TPL
Add Kconfig options so that the RTC can be used in SPL and TPL. This is
helpful for accessing the contents of CMOS RAM, for example.

drivers: rtc: correct week day for mc146818
For qemu-x86 the date command produces wrong days of the week:
Date: 2018-07-06 (Saturday) Time: 18:02:03
Date: 2018-07-07 (unknown day) Time: 21:02

Date: 2018-07-07 (unknown day) Time: 21:02:06
According to a comment in the Linux driver the mc146818 only updates the
day of the week if the register value is non-zero.
Sunday is 1, saturday is 7 unlike in U-Boot (see data sheet
https://www.nxp.com/docs/en/data-sheet/MC146818.pdf).
So let's use our library function to determine the day of the week.
