firmware: arm_scmi: Fix type error assignment in voltage protocol

commit 026d9835b62bba34b7e657a0bfb76717822f9319 upstream.

Fix incorrect type assignment error reported by sparse as:

drivers/firmware/arm_scmi/voltage.c:159:42: warning: incorrect type in assignment (different base types)
drivers/firmware/arm_scmi/voltage.c:159:42: expected restricted __le32 [usertype] level_index
drivers/firmware/arm_scmi/voltage.c:159:42: got unsigned int [usertype] desc_index
