[PATCH 5/8] ARM: AM43xx: Introduce a separate soc_is function for am438x series of SoCs

[Keerthy <j-keerthy-l0cyMroinI0@public.gmane.org>]

EPOS evms are fitted with a separate family of am43xx SoCs and are named
am438x series. Adding a separate soc_is function to identify that
particular series of SoCs. This can be done to avoid unnecessarily
registering hwmods like rtc when not needed on EPOS evms.
