Since ACPI 5.0A it is allowed to disable the ACPI Timer, when the

Starting with Skylake, most platforms (except Xeon-SP) support PM Timer

The FADT contains a flag `ACPI_FADT_PLATFORM_CLOCK` telling the OSPM if
a specification-compliant PM Timer is present. Currently, this flag is
set regardless of the timer being enabled or disabled.
To be specification-compliant, only set that flag, when the hardware PM
Timer is enabled. This changes behaviour of all mainboards defaulting to
USE_PM_ACPI_TIMER=n.
Note: On platforms supporting uCode PM ACPI Timer emulation, this is
required, too, because emulation does not support `TMR_STS`. Any
OS or software checking this flag and thus relying on the overflow
flag would not work (properly).

Note that this is just an example. There are better ways to structure

`cse_fw_update()` is currently checking whether an update is required
by comparing versions once and then again comparing versions later in
`cse_is_downgrade_instance()` to determine if the update is an upgrade
or downgrade. Additionally, if CSE RW partition is corrupt (determined
based on `cse_is_rw_bp_sign_valid()`), `cse_is_downgrade_instance()`
ends up using the corrupted version information to determine if it is
a downgrade instance.
This change reorganizes the firmware update checks to return different
status values:
1. CSE_UPDATE_NOT_REQUIRED: No update required. Versions match.
2. CSE_UPDATE_UPGRADE: Update required and it is an upgrade.
3. CSE_UPDATE_DOWNGRADE: Update required and it is a
downgrade (requires data clear).
4. CSE_UPDATE_CORRUPTED: `cse_is_rw_bp_sign_valid()` failed and hence
requires data clear.
5. CSE_UPDATE_METADATA_ERROR: Unable to read CSE metadata from CBFS.
This change also prepares the file for follow up changes which
completely drop cse_rw_metadata structure.

Currently WWAN_AUX_RST_L is in S5 domain and does not get asserted on
S0i3 entry. Based on the schematics, the pull-down on that signal leads
to 10 mW power leakage on S0i3 entry. Assert the signal on S0i3 entry to
achieve some power savings and de-assert it on S0i3 exit.
BUG=b:195748540
TEST=Build and boot to OS in Guybrush. Ensure that the signal gets
asserted on S0i3 entry and de-asserted on S0i3 exit. Trigger
suspend/resume cycles and ensure that the WWAN module is enumerated
after each cycle.

Add support to handle S0ix entry and exit notifications by adding the
corresponding _DSM functions. The function indices are chosen based on
the Modern Standby BIOS Implementation Guide 56358 Rev. 1.04. Inside
the notification functions perform any mainboard specific S0ix entry and
exit actions.
BUG=b:195748540
TEST=Build and boot to OS in Guybrush. Ensure that the notification
functions are invoked on S0ix entry and exit. Perform suspend/resume
cycles for multiple iterations.
