2020-07-22sb/intel/i82801jx: Drop `docking_supported`Angel Pons
The three mainboards using this southbridge are desktop boards, which are not dockable. The Dell Precision M6400 laptop is dockable, but even though it has an Eaglelake MCH, it uses an i82801ix southbridge instead. So, one could still port that laptop to coreboot after this change! :P Also, drop the now-unnecessary `chip` and `dev` variables.

The three mainboards using this southbridge do not define it. Note that the default value of zero might be wrong, so add a FIXME comment.

2020-07-20src: Report word-sized access for PM1a_EVTAngel Pons
According to the ACPI specification, version 6.3: Accesses to the PM1 status registers are done through byte or word accesses. The same is said about the PM1 Enable registers. Therefore, reporting dword-sized access is wrong and means nothing anyway. Since some other platforms use word-sized access, use word everywhere for consistency. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-07-20src: Make HAVE_CF9_RESET set the FADT reset registerAngel Pons
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as reset register in FADT. How unsurprising. We might as well use that information to automatically fill in the FADT accordingly. So, do it. To avoid having x86-specific code under arch-agnostic `acpi/`, create a new optional `arch_fill_fadt` function, and override it for x86 systems. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-07-20src: Never overwrite `fadt->flags`Angel Pons
Instead, just flip the desired bits using bitwise operations. As this is initially zero, the resulting value is the same. This allows flags to be set from anywhere regardless of execution order.

2020-07-20src: Drop useless PM1b settings from FADTAngel Pons
None of the currently-supported chips has PM1b_EVT nor PM1b_CNT event register blocks. According to the ACPI specification, version 6.3, sections 4.8.1.1 and 4.8.1.2 (PM1 Event/Control Registers): If the PM1b_EVT_BLK is not supported, its pointer contains a value of zero in the FADT. If the PM1b_CNT_BLK is not supported, its pointer contains a value of zero in the FADT. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with PM1b for now. So, drop unneeded writes to PM1b fields. Tested on Asus P8Z77-V LX2 with Linux 5.7.6 and Windows 10 at the end of the patch train, both operating systems are able to boot successfully.

2020-07-20src: Drop useless GPE1 settings from FADTAngel Pons
None of the currently-supported chips has a GPE1 block. The ACPI spec, version 6.3, section 4.8.1.6 (General-Purpose Event Registers) says: If a generic register block is not supported then its respective block pointer and block length values in the FADT table contain zeros. Since the FADT struct defaults to zero in coreboot, we don't need to do anything with GPE1 for now. So, drop the unneeded writes to GPE1 fields.
