scmi: correctly configure MMU for SCMI buffer
Align the MMU area for SCMI shared buffer on section size;
use the ALIGN macro in mmu_set_region_dcache_behaviour call.
Since commit d877f8fd0f09 ("arm: provide a function for boards init
code to modify MMU virtual-physical map") the parameter of
mmu_set_region_dcache_behaviour need to be MMU_SECTION_SIZE
aligned.
Fixes: 240720e9052f ("firmware: scmi: mailbox/smt agent device")
