firmware: arm_scmi: Fix doorbell ring logic for !CONFIG_64BIT [ Upstream commit 7bd39bc6bfdf96f5df0f92199bbc1a3ee2f2adb8 ] The logic to ring the scmi performance fastchannel ignores the value read from the doorbell register in case of !CONFIG_64BIT. This bug also shows up as warning with '-Wunused-but-set-variable' gcc flag: drivers/firmware/arm_scmi/perf.c: In function scmi_perf_fc_ring_db: drivers/firmware/arm_scmi/perf.c:323:7: warning: variable val set but not used [-Wunused-but-set-variable] Fix the same by aligning the logic with CONFIG_64BIT as used in the macro SCMI_PERF_FC_RING_DB().
