[PATCH] thermal/drivers/int340x: fix: update VCoRefLow MMIO bit offset for read

From: Sumeet Pawnikar
Date: Tue Dec 07 2021 - 07:36:04 EST


As part of RFIM validation, found that the register definition VCoRefLow
of the CPU FIVR registers are different. Current implementation reads it
from MMIO offset 0x5A18 and bit offset [12:14]. But the actual correct
register definition is from bit offset [11:13]. Updated to the correct
bit offset.
