AngeloGioacchino Del Regno 45e4c00940 pwm: mtk-disp: Disable shadow registers before setting backlight values ...

[ Upstream commit 36dd7f530a ]

If shadow registers usage is not desired, disable that before performing
any write to CON0/1 registers in the .apply() callback, otherwise we may
lose clkdiv or period/width updates.

Fixes: cd4b45ac44 ("pwm: Add MediaTek MT2701 display PWM driver support")
