drivers: i915: Fix BLC PWM register setup
There is an error in i915_read_blc_pwm_ctl, where the register values
are not being copied correctly. BLC_PWM_CTL and BLC_PWM_CTL2 are
getting mixed up. This patch fixes that so that saveBLC_PWM_CTL2 and
not saveBLC_PWM_CTL is copied to the BLC_PWM_CTL2 register.
