platform/x86/amd/pmc: call amd_pmc_get_ip_info() during driver probe

platform/x86/amd/pmc: call amd_pmc_get_ip_info() during driver probe

In the current code, amd_pmc_get_ip_info() is being called from
amd_pmc_s2d_init() and that code block gets enabled only when the STB is
being enabled.

But the information from amd_pmc_get_ip_info() will be required outside of
STB usecase. Hence move this call into driver probe sequence.
