ACPICA: Do not increment operation_region reference counts for field units

ACPICA commit e17b28cfcc31918d0db9547b6b274b09c413eb70

Object reference counts are used as a part of ACPICA's garbage
collection mechanism. This mechanism keeps track of references to
heap-allocated structures such as the ACPI operand objects.

Recent server firmware has revealed that this reference count can
overflow on large servers that declare many field units under the
same operation_region. This occurs because each field unit declaration
will add a reference count to the source operation_region.

This change solves the reference count overflow for operation_regions
objects by preventing fieldunits from incrementing their
operation_region's reference count. Each operation_region's reference
count will not be changed by named objects declared under the Field
operator. During namespace deletion, the operation_region namespace
node will be deleted and each fieldunit will be deleted without
touching the deleted operation_region object.

ACPICA: Update to GPIO region handler interface.

Changes to correct several GPIO issues:

1) The update_rule in a GPIO field definition is now ignored;
a read-modify-write operation is never performed for GPIO fields.
(Internally, this means that the field assembly/disassembly
code is completely bypassed for GPIO.)

2) The Address parameter passed to a GPIO region handler is
now the bit offset of the field from a previous Connection()
operator. Thus, it becomes a "Pin Number Index" into the
Connection() resource descriptor.

3) The bit_width parameter passed to a GPIO region handler is
now the exact bit width of the GPIO field. Thus, it can be
interpreted as "number of pins".

Overall, we can now say that the region handler interface
to GPIO handlers is a raw "bit/pin" addressed interface, not
a byte-addressed interface like the system_memory handler interface.

ACPI: EC: Limit burst to 64 bits

access_bit_width field is u8 in ACPICA, thus 256 value written to it
becomes 0, causing divide by zero later.

Proper fix would be to remove access_bit_width at all, just because
we already have access_byte_width, which is access_bit_width / 8.
Limit access width to 64 bit for now.
