Pull RTC updates from Alexandre Belloni:
"A few drivers got some nice cleanups and a new driver are making the
bulk of the changes.
Subsystem:
- allow rtc_read_alarm without read_alarm callback
New driver:
- NXP BBNSM module RTC
Drivers:
- use IRQ flags from fwnode when available
- abx80x: nvmem support
- brcmstb-waketimer: add non-wake alarm support
- ingenic: provide CLK32K clock
- isl12022: cleanups
- moxart: switch to using gpiod API
- pcf85363: allow setting quartz load
- pm8xxx: cleanups and support for setting time
- rv3028, rv3032: add ACPI support"
