ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs.

amd/stoneyridge: Indicate STAPM units in their name STAPM devicetree registers do not indicate the unit, which causes confusion. More importantly, the time was assumed to be in seconds when it's actually milliseconds. This caused early STAPM configurations to fail.

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.
