plat: rcar: implement hw_get_random_byte() function
As we now can call ROM API to access hardware random generator, it is
possible to implement generic interface to it, using hw_get_random_byte()
function.
ROM API provides 32 bytes of random data at a time. To optimally use it, we
need to cache received random vector and provide random number bytes from
it one by one.
