Since a custom ibexpeak/nvs.h was already made, an accompanying globalnvs.asl is added here too without chromeos_acpi_t.

There's many copies of this function in the tree. Make the copy in azalia_device.c non-static and rename it to `azalia_set_bits`, then replace all other copies with it. Since azalia_device.c is only built when AZALIA_PLUGIN_SUPPORT is selected, select it where necessary. This has the side-effect of building hda_verb.c from the mainboard directory. If this patch happens to break audio on a mainboard, it's because its hda_verb.c was always wrong but wasn't being compiled.

2020-12-07sb/intel/common: Modify CONFIG_LOCK_MANAGEMENT_ENGINE behaviorSridhar Siricilla
The patch modifies KConfig behaviour if CSE Lite SKU is integrated into the coreboot. When the CSE Lite SKU is integrated, the KConfig prevents writing to ME region but keeps read access enabled. Since CSE Lite driver checks the signature of RW partition to identify the interrupted CSE firmware update, so host must have read access to the ME region. Also, the patch modifies the KConfig's help text to reflect the change.

Setting registers 64h[19:18] = 2 and 68h[14:13] = 3 enables OBFF, and setting registers 64h[19:18] = 0 and 68h[14:13] = 0 disables OBFF. Register at offset 0x64 is DCAP2, and offset 0x68 is DCTL2. However, current code doesn't account for this. The result is that register 64h[19:18] = 2 and 68h[14:13] = 0, which means the hardware is OBFF-capable but support is disabled, which makes no sense.

2020-11-04sb/intel/lynxpoint/acpi/gpio.asl: Simplify constantsAngel Pons
Only LPT-LP includes this file, so `ISLP` is effectively constant. Thus, eliminate some unnecessary if-blocks, since only one branch gets taken.

2020-11-04sb/intel/lynxpoint: Align LP GPIO ACPI with BroadwellAngel Pons
Move the `GWAK` method into the GPIO device, and have lpc.c include the LP GPIO code. All usages of `GWAK` on mainboards need to be updated.

2020-11-04sb/intel/lynxpoint/acpi: Put together LP GPIO codeAngel Pons
Rename `lpt_lp.asl` and place all Lynxpoint-LP GPIO ASL there. It has been named `gpio.asl` to ease diffs between Lynxpoint and Broadwell. Tested with BUILD_TIMELESS=1, Google Panther does not change.

2020-11-03sb/intel/bd82x6x/sata.c: Replace bad uses of `find_resource`Angel Pons
The `find_resource` function will never return null (will die instead). Given that the existing code gracefully handles null pointers already, it is reasonable to replace these function calls with `probe_resource`.
