Enable the ACPI DBG2 table generation for Intel boards. This is
a Microsoft defined ACPI extension that allows an OS to know what
the debug port is on a system when it is not enabled by the
firmware, so it does not show up in the coreboot tables and
cannot be easily found by a payload.
broadwell: Use byte access device, set up only when enabled since
it relies on the port being put in byte access mode and using
this serial port for debug was not standard in this generation.
skylake: Enable for the configured debug port. Skylake uses
intelblocks for UART but not ACPI.
common: Enable for the configured debug port. This affects
apollolake and cannonlake.
Tested by compiling for apollolake/broadwell, tested by reading
the DBG2 ACPI table on kabylake board and using IASL to dump:

Instead of disabling all GPEs during PMC init in bootblock, this
change moves it to pmc_fill_power_state which allows romstage to
correctly fill up GPE_EN registers in chipset_power_state. This is
essential for correctly identifying the wake source.
Disabling all GPEs was added recently in change 74145f76
(intel/common/pmc: Disable all GPEs during pmc_init) because keeping
GPEs enabled in coreboot while enabling SMI could lead to
side-effects as explained in the change. Moving pmc_disable_all_gpe to
pmc_fill_power_state should be safe as that happens before SMI is
enabled in coreboot.
TEST=Verified that GPE-based wake source is correctly
identified. Also, no issues observed while resuming from S3.

If GPEs are not cleared during pmc_init, it could result in issues if
standard wake events are generated while coreboot is
initializing. e.g. (Observed on soraka):
1. Suspend to S3
2. Lidclose
3. Lidopen
4. EC wakes up the host using WAKE# pin
5. On wakeup, pmc_init occurs which does not clear GPEs
6. MP init enables SMI
7. In order to add wake event to elog, coreboot sets wake mask on the
EC, which causes the EC to assert WAKE#.
8. Since WAKE# is asserted, it results in an SMI#. However, EC does
not de-assert WAKE# until host queries and clears the host event
bit (which does not happen since coreboot is stuck in handling the
SMIs).
This is one of the issues that can occur when GPEs are unnecessarily
enabled in coreboot. Before the move to PMC common library, SKL PMC
driver set all GPEs to 0 and hence this issue did not occur.
This change explicitly disables all GPEs during pmc init in order to
avoid any side-effects.
