In preparation to follow-up commits, rename the mainboard folder from t440p to haswell, which will have more variants later.

2021-06-22mb/lenovo/t440p: Disable second PEG deviceAngel Pons
PEG bifurcation is strapped to x8/x8 on this board, but only the first port is used. Disable the PEG device at 00:01.1 because it is unused. Should fix booting with commit ae999503f62ef8a3b9b2756a2810d29c383a009e (nb/intel/haswell/pcie.c: Add missing pre-ASPM init). The `config_of()` function call added in that commit makes coreboot die if any PEG device that is enabled by strapping is not present in the devicetree. While it is true that the PEG code should not use `config_of()`, this PEG device should still be disabled on this board as it is never used.

2021-01-01nb/intel/hsw,soc/intel/{bdw,skl,apl},mb/*: unify dt panel settingsMichael Niewöhner
There are multiple different devicetree setting formats for graphics panel settings present in coreboot. Replace the ones for the platforms that already have (mostly) unified gma/graphics setup code by a unified struct in the gma driver. Hook it up in HSW, BDW, SKL, and APL and adapt the devicetrees accordingly. Always ensure that values don't overflow by applying appropriate masks. The remaining platforms implementing panel settings (GM45, i945, ILK and SNB) can be migrated later after unifying their gma/graphics setup code.

2021-01-01soc/intel/bdw,nb/intel/hsw: convert panel delays to ms representationMichael Niewöhner
For easier review of the switch to a new register struct in the follow-up change, the panel delay times get converted from destination register raw format to milliseconds representation in this change. Formula for conversion of power cycle delay: gpu_panel_power_cycle_delay_ms = (gpu_panel_power_cycle_delay - 1) * 100 Formula for all others: gpu_panel_power_X_delay_ms = gpu_panel_power_X_delay / 10 The register names gain a suffix `_ms` and calculation of the destination register raw values gets done in gma code now.

2020-07-12haswell: Move some MRC settings to devicetreeAngel Pons
There's no generic way to tell whether a mainboard has an EC or not. Making Kconfig symbols for these options seems overkill, too. So, just put them on the devicetree. Also, drop unnecessary assignments when the board's current value is zero, as the struct defaults to zero already.

2020-03-29nb/intel/haswell: Implement proper backlight PWM configNico Huber
Further backport the backlight-PWM handling from Skylake. Beside configuring the PWM frequency in Hz, we also use the PCH's logic for the brightness setting via BLM_PCH_OVERRIDE_ENABLE. Linux would toggle it anyway and that might confuse our ASL code. We assume that the 183Hz value that was set before for Slippy variants was overridden by Linux with the 200Hz VBT value, like it was for the Broadwell Chromebooks. So we set 200Hz for them in the devicetrees. The calculated value for the T440p of 220Hz seems sane and also matches the VBT.
