ACPICA: Disable preservation of SCI enable bit (SCI_EN)

Preserving this bit breaks some machines. Not preserving this bit
seems to work OK in all cases, even though this goes against the
ACPI spec.

ACPICA: Invalidate DdbHandle after table unload

Mark the DdbHandle as invalid after the table it refers to is
unloaded. This is needed because the handle itself may not be
deleted after the table unload, depending on whether it has been
stored in a named object by the caller.

ACPICA: Fix allowable release order for ASL mutex objects

The ACPI 4.0 specification has been changed to make the SyncLevel
for mutex objects more useful. When releasing a mutex, the
synclevel of the mutex must now be the same as the current sync
level. This makes more sense. This change updates the code to
match the spec.

ACPICA: Mutex support: Fix release ordering issue and current sync level

Fixes a problem where if multiple mutexes of the same sync level
are acquired but then not released in strict opposite order, the
current sync level becomes confused and can cause errors.

ACPICA: Fix possible warnings for ACPI_THREAD_ID on 64-bit build

Warnings can be generated for printf-like statements that output
the ACPI_THREAD_ID on 64-bit builds, since this type can expand
to 64-bits depending on how it is defined. Use the %p format
specifier to allow the output to automatically expand to 64 bits.
