to look at the new patch set (#5).

Change subject: mb/google/kahlee: edp panel initialization time tuning
......................................................................

mb/google/kahlee: edp panel initialization time tuning

1.adding 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_BKLTEM_L,so to change APU_EDP_BKLTEN_L to low as default,
  thus we can control the delay time by config APU_DP_VARY_BL.

BUG=b:118011567
TEST=emerge-grunt coreboot
