We suggest client store the event information in device node,

The return value of rproc_da_to_va would probably be device memory. Add
__iomem annotation to it.

I feel that there might be more things that need to be changed
(especially for the carveouts things). I didn't change them since I
don't know how to test that part
Use memset_io and memcpy_toio instead of memset and memcpy in
rproc_elf_load_segments, since the target ptr may be device memory.

Add a simple rpmsg support for mt8183 SCP, that use IPI / IPC directly.
Lots of TODO, and I'm not sure on all file / type / variable namings.

Changes from v2:
- Unregiser IPI handler on unprepare.
- Lock the channel list on operations.
- Move SCP_IPI_NS_SERVICE
Since a SCP and EC would both exist on a system, and use the cros_ec_dev
driver, we need to differentiate between them for the userspace, or they
would both be registered at /dev/cros_ec, causing a conflict.

Changes from v2:
- No change. I realized that for this patch series, there's no need to
add anything under the mt8183-scp node (neither the mt8183-rpmsg or
the cros-ec-rpmsg)
The mtk_thermal struct contains a 'struct mtk_thermal_bank banks[];',
but the allocation only allocates sizeof(struct mtk_thermal) bytes,
which cause out of bound access with the ->banks[] member. Change it to
a fixed size array instead.
