plat: rcar: add support for ROM API calls including HW RNG

RCAR Gen3 SoCs have public ROM API functions that provide access to various
security-related features, including access to hardware random number
generator.

This patch adds both generic ROM API interface and wrapper function for
ROM_GetRndVector() call.

As ROM API code is written with identity mapping in mind, we can't call
those function with MMU enabled. So we need a special trampoline function
that would disable MMU, save state and jump to ROM API code.

Beginning with the latest revisions (H3 ES3.0, M3 ES1.1, etc) of Renesas
SoCs, ROM API addresses are fixed, but prior to that each family had own
address, so we need to maintain table of all possible addressed and select
correct one in runtime.
