soc/amd/common/block/cpu/noncar/write_resume_eip: use raw MSR data
Since mst_t is a union of the struct containing the lower and higher 32
bits and the raw 64 bit value, the address of the bootblock_resume_entry
can be directly written to the raw value instead of needing to split it
into the lower and higher 32 bits and assigning those separately.
