ACPI: CPPC: Fix _CPC register setting issue
[ Upstream commit 2388b266c9fcc7c9169ba85c7f9ebe325b7622d7 ]
Since commit 60949b7b8054 ("ACPI: CPPC: Fix MASK_VAL() usage"), _CPC
registers cannot be changed from 1 to 0.
It turns out that there is an extra OR after MASK_VAL_WRITE(), which
has already ORed prev_val with the register mask.
Remove the extra OR to fix the problem.
