The patch adds rtc hwmod. RTC module The RTC module is physically
present on the AM438x SoC used on AM43X-EPOS-EVM, but it is permanently
disabled. A secure RTC is used instead on these devices, where needed.
. Hence adding it selectively using a seprate list to get RTC Module
functional on the other am43x SoCs used on am437x-gp-evm and
am437x-sk-evm.

No Public TRM is available for AM438x SoC as of now.
