pwm: mtk_disp: Fix the disable flow of disp_pwm
[ Upstream commit bc13d60e4e1e945b34769a4a4c2b172e8552abe5 ]
There is a flow error in the original mtk_disp_pwm_apply() function.
If this function is called when the clock is disabled, there will be a
chance to operate the disp_pwm register, resulting in disp_pwm exception.
Fix this accordingly.
Fixes: 888a623db5d0 ("pwm: mtk-disp: Implement atomic API .apply()")
