From: xinlei lee <xinlei.lee@xxxxxxxxxxxx>
In the original mtk_disp_pwm_get_state() function, the result of reading
con0 & BIT(0) is enabled as disp_pwm.
In order to conform to the register table, we should use the disp_pwm
base address as the enabled judgment.
Fixes: 3f2b16734914 ("pwm: mtk-disp: Implement atomic API .get_state()")
