soc/amd/mendocino: Reinterpret smu_power_and_thm_limit
The FSP will return the TDP in the format 0xX0000, where 'X' is the
value we're interested in. For example: 0xF0000 (15W), 0x60000 (6W).
Re-interpret the value so the caller just sees the TDP directly, without
needing to re-interpret things themselves.
BUG=b:253301653
TEST=Manually verify value is correct
