ACPICA: FADT parsing changes and fixes

1) Update the register lengths for the PM1 event blocks. The
length must be divided by two in order to use these to access
the status registers.
2) Add run-time option to use default register lengths to override a

3) Add warning message if any of the X64 address structures contain a length
that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.

The struct acpi_prt_entry is used only in pci_irq.c, so there's no
need for the declaration to be public.  This patch moves it into
pci_irq.c.

that management.  And we don't have to call acpi_get_irq_routing_table()

ACPI: Do not modify SCI_EN directly

the hardware, which sets this flag to inform the kernel that ACPI is
enabled.  For this reason, we shouldn't try to modify SCI_EN

lower-level resume code takes care of enabling ACPI in case it hasn't

Boards should know when QE_USB is used, so that they can configure USB
clocks and pins.

Another option would be to add 'select QE_USB' into USB_GADGET_FSL_QE,
but selects are evil since they don't support dependencies.

The API relies on the fact that QE gpio controllers are registered. If
they aren't, the API won't work (gracefully though).

There is one caveat though: if anybody occupied the node->data before us,
or overwrote it, then bad things will happen. Luckily this is all in the
platform code that we fully control, so this should never happen.

I could implement more checks (for example we could create a list of
successfully registered QE controllers, and compare the node->data in the
qe_pin_request()), but this is unneeded if nobody is going to do silly
