H A Drtc-pcf2127.cdiff afc505bf9039caf5a377d8b9705ef42f6d4ac7d4 Thu Jun 22 09:57:54 CDT 2023 Hugo Villeneuve <hvilleneuve@dimonoff.com> rtc: pcf2127: add support for PCF2131 RTC

This RTC is very similar in functionality to the PCF2127/29.

Basically it:
-supports two new control registers at offsets 4 and 5
-supports a new reset register (not implemented in this driver)
-supports 4 tamper detection functions instead of 1
-has no nvmem (like the PCF2129)
-has two output interrupt pins

Because of that, most of the register addresses are very different,
although they still follow the same layout. For example, the tamper
registers have a different base address, but the offsets are all the same.
