On armv8r there is no firmware and the system timer must be initialized by the hypevisor. There are multiple cases from where to get the frequecy: (i) it might be fixed already in the hardware, or (ii) it can be retrieved from the plaform level timer if such timer is defined, or (iii) the hypervisor must know by default which is it (which must be defined by platform descrption from the
PLAT_GENERIC_TIMER_FREQ_HZmacro). This PR handles all this cases.
