[ Upstream commit 658c82caffa042b351f5a1b6325819297a951a04 ]
The gdsc_init() function will rewrite the CLK_DIS_WAIT field while registering the GDSC (writing the value 0x2 by default). This will override the setting done in the driver's probe function.
Set cx_gdsc.clk_dis_wait_val to 8 to follow the intention of the probe function.
