soc/intel/tigerlake: Configure TCSS D3Hot and D3Cold
Update configuration for both of TCSS D3Hot and D3Cold. It is expected
D3Hot is enabled for all platforms. Because there are known limitations
for D3Cold enabling on pre-QS platform, this change reads cpu id and
disables D3Cold for pre-QS platform. For QS platform, D3Cold is
configured to be enabled.
BUG=None
TEST=Verified D3Hot is enabled, D3Cold is disabled for pre-QS (cpu:806c0)
and enabled for QS (cpu:0x806c1).
