ACPI: Fix possible recursive locking in hwregs.c
Calling pm-suspend might trigger a recursive lock in it's code path.
In function acpi_hw_clear_acpi_status, acpi_os_acquire_lock holds
the lock acpi_gbl_hardware_lock before calling acpi_hw_register_write(),
then without releasing acpi_gbl_hardware_lock, this function calls
acpi_ev_walk_gpe_list, which tries to hold acpi_gbl_gpe_lock.
Both acpi_gbl_hardware_lock and acpi_gbl_gpe_lock are at same
lock-class and which might cause lock recursion deadlock.
Following patch fixes this scenario by just releasing
acpi_gbl_hardware_lock before calling acpi_ev_walk_gpe_list.
Changes since v0(https://lkml.org/lkml/2011/9/21/355):
- Fix changelog, thanks to Lin Ming.
Changes since v1 (https://lkml.org/lkml/2011/11/3/89):

ACPICA: Change handling of PM1 Status register ignored bit
Ignored bits must be preserved according to the ACPI spec.
Usually this means a read/modify/write when writing to the
register. However, for status registers, writing a one means
clear the event. Writing a zero means preserve the event (do not
clear.) This behavior is clarified in the ACPI 4.0 spec, and the
ACPICA code now simply always writes a zero to the ignored bit.

ACPICA: Add function to handle PM1 control registers
Added acpi_hw_write_pm1_control. This function writes both of the PM1
control registers (A/B). These registers are different than than
the PM1 A/B status and enable registers in that different values
can be written to the A/B registers. Most notably, the SLP_TYP
bits can be different, as per the values returned from the _Sx
predefined methods.

ACPICA: For PM1B registers, do not shift value read or written
The PM1B registers are mirrors of the PM1A registers with
different bits actually implemented. From the ACPI specification:
"Although the bits can be split between the two register blocks
(each register block has a unique pointer within the FADT), the bit
positions are maintained. The register block with unimplemented
bits (that is, those implemented in the other register block)
always returns zeros, and writes have no side effects"
