mb/google/kahlee: Tune eDP panel initialization time
1. Add two parameters for panel initialization timing.
> lvds_poseq_varybl_to_blon
> lvds_poseq_blon_to_varybl
2. The BL_PWM is controlled by APU_EDP_BKLTEN_L/APU_DP_VARY_BL/
EDP_BKLTEN_L, so move APU_EDP_BKLTEN_L to early init stage,
and be enabled depends on SKU, thus we can control the delay
time by config APU_DP_VARY_BL.
BUG=b:118011567
