Merge ACPI core fix to avoid calling dmi_check_system() on non-x86.

* acpi-bus:
  ACPI / bus: Only call dmi_check_system() on X86

Commit 12864ff8545f (ACPI / LPSS: Avoid PM quirks on suspend and resume
from hibernation) bypasses lpss quirks for S3 and S4, by setting a flag
for S3/S4 in acpi_lpss_suspend(), and check that flag in
acpi_lpss_resume().

But this overlooks the boot case where acpi_lpss_resume() may get called
without a corresponding acpi_lpss_suspend() having been called.

Thus force setting the flag during boot.

Calling dmi_check_system() early only works on X86. Other
architectures initialize the DMI subsystem later so it's not
ready yet when ACPI itself gets initialized.

In the best case it results in a useless call to a function which
will do nothing. But depending on the dmi implementation, it could
also result in warnings. Best is to not call the function when it
can't work and isn't needed.

Additionally, if anyone ever needs to add non-x86 quirks, it would
surprisingly not work, so document the limitation to avoid confusion.

My fix for a recursive Kconfig dependency caused another issue where the
ACPI specific options end up in the top-level menu in 'menuconfig'. This
was an unintended side-effect of having a silent option between
'menuconfig ACPI' and 'if ACPI'.

Moving the ARCH_SUPPORTS_ACPI symbol ahead of the ACPI menu solves that
problem and restores the previous presentation.

  ACPI / PMIC: CrystalCove: Extend PMOP support to support all possible fields

This is unnecessary and triggers a warning in the hypervisor.

Often systems have more processor entries in their ACPI tables than are
actually installed/active. The ACPI_STA_DEVICE_PRESENT bit cannot be
reliably used, but the ACPI_MADT_ENABLED bit can. In order to not
introduce new functions in the main ACPI processor driver code, simply
use acpi_get_phys_id(), which does more than we need, but which checks
the MADT enabled bit in the process. Any CPU for which we can't
determine the APIC ID is unlikely to work properly anyway, so the extra
checks done by acpi_get_phys_id() should do no harm.
