clk: qcom: gcc-sa8775p: Update the GDSC wait_val fields and flags

Browse Source 
Update the GDSC wait_val fields as per the default hardware values as
otherwise they would lead to GDSC FSM state to be stuck and causing
failures to power on/off. Also add the GDSC flags as applicable and
add support to control PCIE GDSC's using collapse vote registers.
