Export function rtc_month_days() for reuse in the UEFI subsystem.

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.

Variable 'days' must be defined as signed int. Otherwise the conversion
fails for some dates, e.g. 2004-08-25. Cf function rtc_time64_to_tm() in

Improvements:
- RK3188 USB-UART functionality
- errors triggering a hard-stop in SPL on the RK3399 are reported
- Rockchip RV1108 (SoC) support
- MicroCrystal RV3029 (RTC) DM driver
Fixes:
- RK3188 early UART setup
- limit SD-card frequency to 40MHz on the RK3399-Q7
- MIPI fixes
- RK3399 CPUB clock initialisation

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.

This can be used for device register access from board code.
This allows access to capabilities in the RTC chip not abstracted in

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: 21:02:06
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).

QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC.
The patch sets the base address in the board include file according to the
definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig
option for the existing driver, and enables the RTC driver in
qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command.
We need an RTC to provide the GetTime() runtime service in the UEFI
subsystem.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
