Subject: [PATCH 2/2] clk: qcom: gdsc: Update the status poll timeout for
 GDSC

During the GDSC FSM state, the GDSC hardware waits for an ACK from the
respective subsystem core. In some scenarios, this ACK can be delayed.
To handle such delays, increase the GDSC status poll timeout from 1500us
to 2000us as per the design recommendation.
