Nathan Chancellor 0a6d3038d9 dmaengine: qcom: Always inline gpi_update_reg 
When building with CONFIG_UBSAN_UNSIGNED_OVERFLOW, clang decides not to
inline gpi_update_reg, which causes a linkage failure around __bad_mask:

ld.lld: error: undefined symbol: __bad_mask
>>> referenced by bitfield.h:119 (include/linux/bitfield.h:119)
>>>               dma/qcom/gpi.o:(gpi_update_reg) in archive drivers/built-in.a
>>> referenced by bitfield.h:119 (include/linux/bitfield.h:119)
>>>               dma/qcom/gpi.o:(gpi_update_reg) in archive drivers/built-in.a

If gpi_update_reg is not inlined, the mask value will not be known at
compile time so the check in field_multiplier stays in the final
object file, causing the above linkage failure. Always inline
gpi_update_reg so that this check can never fail.
