Subject: [PATCH] arch: cache: cp15: Add mmu_set_region_dcache_behaviour() when
SYS_DCACHE_OFF is enable
Fix following compilation issue when SYS_DCACHE_OFF is enable:
drivers/misc/scmi_agent.c:128: undefined reference to `mmu_set_region_dcache_behaviour'
when SYS_DCACHE_OFF is enable, mmu_set_region_dcache_behaviour() must be
defined.
