soc/amd: pass pstate_msr union to get_pstate_core_[freq,power]

Browse Source 
Since we already have and use the pstate_msr union in get_pstate_info,
also pass it directly to the get_pstate_core_freq and
get_pstate_core_power function calls avoids having to sort-of convert
the msr_t type parameter in the implementations of those two functions.
In amdblocks/cpu.h a forward declaration of the pstate_msr union is used
since soc/msr.h doesn't exist in the two pre-Zen SoCs that also include
amdblocks/cpu.h.
