rtc: rx8025: add support for EPSON RX8035.

The RX8035 is a newer model from EPSON which is
very similar in operation to the RX8025.

The changes mirror similar ones that will be
in Linux 5.15:

The UBOOT_DRIVER ID has also been corrected, previously
it declared itself as rx8010sj_rtc which is a different driver.
