soc/amd/cezanne: Turn off gpp clock request for disabled devices
The current behavior does not actually check if a device is present
before enabling the corresponding gpp_clkx_clock_request_mapping bits
which may cause issues with L1SS. This change sets the corresponding
gpp_clkx_clock_request_mapping to off if the corresponding device is
disabled.
BUG=b:202252869
TEST=Checked that value of GPP_CLK_CNTRL matched the expected value
when devices are enabled/disabled, checked that physically removing a
device that is marked as enabled also disables the corresponding clk req
