rtc: pcf2127: fix alarm handling
Fix multiple issues when handling alarms:
- Use threaded interrupt to avoid scheduling when atomic
- Stop matching on week day as it may not be set correctly
- Avoid parsing the DT interrupt and use what is provided by the i2c or
spi subsystem
- Avoid returning IRQ_NONE in case of error in the interrupt handler
- Never write WDTF as specified in the datasheet
- Set uie_unsupported, as for the pcf85063, setting alarms every seconds
is not working correctly and confuses the RTC.
