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.

Use readl_poll_timeout() from <iopoll.h> instead of using custom poll
loops.
The timeout settings are different, but that shouldn't be much of a
problem. Instead of polling 10000 times in a close loop, it polls for
one millisecond.

Switch the driver from legacy gpio API that is deprecated to the newer
gpiod API that respects line polarities described in ACPI/DT.
This makes driver use standard property name for its gpios
("rtc-*-gpios" vs "gpios-rtc-*"), however there is a quirk in gpiolib
to also recognize legacy names and keep compatibility with older DTSes:

Since commit c8d523a4b053 ("drivers/rtc/rtc-pm8xxx.c: rework to support

for a driver lock.
Specifically, the rtc ops are serialised by rtc core and the interrupt
handler only unconditionally disables the alarm using the alarm_ctrl
register.
Note that since only the alarm enable bit of alarm_ctrl is used after
enabling the RTC at probe, the locking was not needed when doing open
coded read-modify-write cycles either.

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).

Since the WKTMR hardware block cannot be disabled it is necessary
for the driver to accommodate for associated timing hazards. This
commit targets the following possibilities:
A possible race between clearing a wktmr event and the alarm expiring
is made one-sided by setting the alarm to its maximum value before
clearing the event.
Programming alarm values close to the current time may not trigger
events if the counter advances while the alarm is being programmed.
After programming an alarm, a check is made to ensure that it is
either in the future or an expiration event is pending.

simplify the source code. They are performed here to simplify
review and reduce confusion with other changes in this set.
Since set_alarm includes the alarm_irq_enable functionality call
it directly from that function for simplicity (even though it
does nothing at the moment). The order of the declarations is
changed to prevent the need for a prototype.
The function device_init_wakeup() is used to replace the
functions device_set_wakeup_capable() and device_wakeup_enable()
