Sometimes ROM_GetRndVector() function returns an error, which causes
OP-TEE panic down the call path, as OP-TEE can't handle errors from
the hardware random number generator. As a workaround, we can try to
repeat call to the ROM_GetRndVector() because it succeeds on the next
try.
Anyways, this hardly can be considered as a normal behavior so it is
better to disable HW RNG by default, which will be done in a separate
patch.
