rockchip: rk3588: Map SCMI shared memory area as non-cacheable
The SCMI shared memory area is no longer automatically marked as
non-cacheable after the commit a5a0134570c8 ("firmware: scmi: Drop
mmu_set_region_dcache_behaviour() misuse").
This change in behavior cause Rockchip RK3588 boards to fail boot with:
SoC: RK3588
DRAM: 8 GiB
scmi-over-smccc scmi: Channel unexpectedly busy
scmi_base_drv scmi-base.0: getting protocol version failed
scmi-over-smccc scmi: failed to probe base protocol
initcall_run_r(): initcall initr_dm() failed
### ERROR ### Please RESET the board ###
Update the memory mapping on RK3588 to mark the SCMI shared memory area
as non-cacheable to fix the SCMI shared memory based transport issue
that prevented RK3588 boards from booting.
