[PATCH V1 2/2] backlight: qcom-wled: Correct the sync_toggle sequence

[Kiran Gunda]

Currently the FSC SYNC_BIT and MOD_SYNC_BIT are toggled
from 1 to 0 to update the FSC and brightenss settings.
Change this sequence form 0 to 1 as per the hardware team
recommendation to update the FSC and brightness correctly.
