u-boot does not appear to support AM62 RTCSS Scratch registers (unless they are identical to AM33, TBD.)

At the very least this codebase will need to add support for the correct platform compat strings.

From AM62x Sitara Processors Technical Reference Manual (Rev. B):

14.8.7.3.12.1 RTC_RTC_SCRATCH0_N Register (Offset = 30h) [reset = 0h ]

Instance Name    Physical Address
WKUP_RTCSS0      2B1F 0030h
Bit Field Type Reset Description
31:0 SCRATCH0 R/W Xh The scratch0 holds data in the battery backed domain for use by the device when powered on. This would typically be used to store signatures other information of similar ilk.

For posterity: I checked the AM64 TRM and it does not even appear to have the RTCSS register.
