[PATCH v4 0/4] rtc: rzn1: cleanups, R-Car X5H enablement

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

This series adds RTC support for the Renesas R-Car X5H SoC.

Changes since v3:
* clear RTC_FEATURE_UPDATE_INTERRUPT when no irqs
* added tags

Thanks for all the reviews of v3!

These patches have been tested on the original RZ/N1D board and the new
X5H Ironhide board. 'rtctest' passed on both SoCs. On X5H, some tests
are skipped, of course, because no alarms are supported.

'dt_binding_check' and 'dtbs_check' did not find any issues, for both,
RZ/N1D and R-Car X5H. I also verified for both that it rightfully
complains when irqs are different from what is expected.

A branch can be found here:

Looking forward to comments.
