The new macro set has a consistent namespace and uses C99 initializers
instead of the grufty C89 ones.
Rename the local macro wrapper to X86_MATCH for consistency. It stays for
readability sake.

Recently produced GPD win devices have a new BIOS, research into the
changes in this BIOS has found a ChangeLog which shows that the disabling
of the KIOX000A node has been done starting with the 20170221 version.
Unfortunately the GPD pocket uses the exact same DMI strings as the win
and its BIOS was copy-pasted from the GPD win, so it has a disabled
KIOX000A node which we should not enable, so we need to check for the
exact BIOS date.
This commit adds 2 extra entries to the always_present_ids quirk table
with bios_date matches for the older also affected and the latest BIOS.

The GPD win BIOS dated 20170320 has disabled the accelerometer, the

I see no other way to keep the accelerometer working under Windows then
adding it to the always_present_ids array.

The _STA method of the Venue 11 Pro 7130 touchscreen has this ugliness:
Method (_STA, 0, NotSerialized) // _STA: Status
{
If ((SDS1 & One) == One)
{
If (RST1 == Zero)
{
Return (0x0F)
}
ElseIf (RST2 == Zero)
{
RST2 = One
TMRV = Timer
}
Else
{
Local0 = ((Timer - TMRV) / 0x2710)
If (Local0 > TMRI)
{
RST2 = Zero
RST1 = Zero
}
}
}
Else
{
Return (Zero)
}
}
Whereby RST1 gets set by _SB.PCI0.GFX0.LCD.LCD1._ON, this means that
after RST1 has been set first _STA must be called to set TIMER and
then after enough time has elapsed _STA must be called twice more, once
to clear RST1 and once to finally return 0xf before the touchscreen will
show up. Which is just crazy.
This commit adds an always_present_ids entry for the SYNA7500 touchscreen
ACPI node, together with a DMI match for the Venue 11 Pro 7130, fixing the
touchscreen not working on this device.

On some x86 systems the DSDT hides APCI devices to work around Windows
driver bugs. On one such system the device is even hidden until a certain
time after _SB.PCI0.GFX0.LCD.LCD1._ON gets called has passed *and*
_STA has been called at least 3 times since. TL;DR: it is a mess.
Until now the always_present_id matching was used to force status
for a whole class of devices, e.g. always enable PWM1 on CHerry Trail
devices.
This commit extends the always_present_id matching code to optionally
also check for a DMI match so that we can also add system specific
quirks to the always_present_id array.

Several Bay / Cherry Trail devices (all of which ship with Windows 10) hide
the LPSS PWM controller in ACPI, typically the _STA method looks like this:
Method (_STA, 0, NotSerialized) // _STA: Status
{
If (OSID == One)
{
Return (Zero)
}
Return (0x0F)
}
Where OSID is some dark magic seen in all Cherry Trail ACPI tables making
the machine behave differently depending on which OS it *thinks* it is
booting, this gets set in a number of ways which we cannot control, on
some newer machines it simple hardcoded to "One" aka win10.
This causes the PWM controller to get hidden, which means Linux cannot
control the backlight level on cht based tablets / laptops.
Since loading the driver for this does no harm (the only in kernel user
of it is the i915 driver, which will only uses it when it needs it), this
commit makes acpi_bus_get_status() always set status to ACPI_STA_DEFAULT
for the LPSS PWM device, fixing the lack of backlight control.
