PS1, Line 188: soc_get_rtc_failed
`soc_get_rtc_failed()` gets called only in ramstage. So, clearing `RTC_BATTERY_DEAD` here wouldn't really fix the boot loop you mentioned in commit message.

If you decide to move this to `vbnv_cmos_failed()` you will have to ensure that the cmos_init() flow still looks correct.
