[PATCH 22/30] Utilities: Fix missing parentheses in ACPI_GET_BITS()/ACPI_SET_BITS()

[Lv Zheng]

Some compilers require parentheses to be enforced in the macro definition,
so that the macro caller side can be simpler.

This patch fixes this kind of macro issue in
ACPI_SET_BITS()/ACPI_GET_BITS(). Lv Zheng.
