mb/google/brya: set PL4 value dynamically for thermal
Set PL4 value dynamically for brya board based on CPU SKUs
which is detectable at runtime.

BRANCH=None
TEST=Build FW and test on brya0 with below messages,
On brya (282):
Overriding DPTF power limits PL1 (3000, 15000) PL2 (39000, 39000) PL4 (100000)
On brya (482):
Overriding DPTF power limits PL1 (4000, 28000) PL2 (43000, 43000) PL4 (105000)
