On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which the
driver can take into account.
Add support for storing a 32-bit offset from the Epoch in an nvmem cell
so that the RTC time can be set on such platforms.

This adds support for the 256-byte internal RAM. There are two windows
which can be used to access this RAM: 64 bytes at 0x40 (the "standard"
address space) and 128 bytes at 0x80 (the "alternate" address space). We
use the standard address space because it is also accessible over SPI
(if such a port is ever done). We are limited to 32-byte reads for SMBus
compatibility, so there's no advantage to using the alternate address
space.
There are some reserved bits in the EXTRAM register, and the datasheet
doesn't say what to do with them. I've opted to skip a read/modify/write
and just write the whole thing. If this driver is ever converted to
regmap, this would be a good place to use regmap_update_bits.

There are cases where the EFI runtime services may end up in a funny
state, e.g., due to a crash in the variable services, and this affects
other EFI runtime services as well.
That means that, even though GetTime() should not return an error, there
are cases where it might, and there is no point in logging such an
occurrence multiple times.
This works around an issue where user space -apparently- keeps hitting
on /dev/rtc if it fails to read the h/w clock, resulting in a tsunami of
log spam and a non-responsive system as a result.

On JZ4770 and JZ4780, the CLK32K pin is configurable. By default, it is
configured as a GPIO in input mode, and its value can be read through
GPIO PD14.
With this change, clients can now request the 32 kHz clock on the CLK32K
pin, through Device Tree. This clock is simply a pass-through of the
input oscillator's clock with enable/disable operations.
This will permit the WiFi/Bluetooth chip to work on the MIPS CI20 board,
which does source one of its clocks from the CLK32K pin.

RTC core never calls rv8803_set_alarm with an invalid alarm time,
so if an invalid alarm time > 0 is set, external factors must have
corrupted the RTC's alarm time and possibly other registers.
Play it safe by marking the date/time invalid, so all registers are
reinitialized on a ->set_time.
This may cause existing setups to lose time if they so far set only
date/time, but ignored that the alarm registers had an invalid date
value, e.g.:
rtc rtc0: invalid alarm value: 2020-3-27 7:82:0
These systems will have their ->get_time return -EINVAL till
->set_time initializes the alarm value (and sets a new time).
