Partially reverted commit "soc: qcom: cmd-db: drop unused
functions" by restoring only the cmd_db_read_slave_id() and
cmd_db_read_aux_data() functions, which were removed in that
commit. These functions are required for the RPMH Power Domain
Driver.

On at least SM8650 this region might not be included in the memory map.
Use the new mmu_map_region() helper to map it during bind().

memcmp() can cause aborts on some platforms and generally seems to be
the wrong approach here. Use strncmp() instead which is more correct.

Keep the header pointer in the .data section so we don't initialize it
again after relocation, adjust cmd_db_get_header() to work with the
U-Boot API, and skip validating the header since all cmd-db users are
children of the rpmh-rsc and those children will only probe if cmd-db
initializes successfully.

Integrate cmd-db into the U-Boot driver model.
This is just a wrapper around an in-memory database, so we just need to
get the address and validate that cmd-db is there.
Since cmd_db_header will be stored in the .data section we can skip
bind if it's already set.

Due to our simpler rpmh-rsc driver and lack of debugfs, we don't need
quite a few cmd-db functions, just drop them.
