7062d4e815 scmi: translate the resource only when livetree is not activated
Call the translation function on the ofnode_read_resource result only
when the livetree is not activated.

Today of_address_to_resource() calls ofnode_read_resource() for livetree
support and fdt_get_resource() when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required when livetree is activated but this address
translation is already done by ofnode_read_resource().

2a3f161c8b 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 d877f8fd0f ("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.

240720e905 firmware: scmi: mailbox/smt agent device
This change implements a mailbox transport using SMT format for SCMI
exchanges. This implementation follows the Linux kernel and
SCP-firmware [1] as references implementation for SCMI message
processing using SMT format for communication channel meta-data.

Use of mailboxes in SCMI FDT bindings are defined in the Linux kernel
DT bindings since v4.17.
