[PATCH v3 5/7] platform/x86/amd/pmf: Use upper/lower_32_bits() in amd_pmf_set_dram_addr()

Replace the open coded manual bit shifting used to split a 64-bit
physical address into its high and low 32-bit halves with the standard
kernel helpers upper_32_bits() and lower_32_bits().

No functional changes.
