[PATCH v2 2/2] ufs: mcq: Convert MCQ_CFG_n to a inline function

From: Minwoo Im
Date: Sun May 19 2024 - 18:36:21 EST


Unlike the previous patch, this patch does not fix any issues, but,
inline functions are much more preferred over macros, so this patch
converted MCQ_CFG_n macro in ufs-mcq to an inline function along with
the previous patch.
