Taniya Das 6e6fec3f96 clk: qcom: dispcc: Update the transition delay for MDSS GDSC
On SC7180 we observe black screens because the gdsc is being
enabled/disabled very rapidly and the GDSC FSM state does not work as
expected. This is due to the fact that the GDSC reset value is being
updated from SW.

The recommended transition delay for mdss core gdsc updated for
SC7180/SC7280/SM8250.

Fixes: dd3d066221 ("clk: qcom: Add display clock controller driver for SC7180")
Fixes: 1a00c962f9 ("clk: qcom: Add display clock controller driver for SC7280")
Fixes: 80a18f4a85 ("clk: qcom: Add display clock controller driver for SM8150 and SM8250")
