[PATCH 1/6] remoteproc: amd_mbv_bram: Bound device name formatting

[Ben Levinsky]

rproc_mem_entry_init() interprets its name argument as a printf format
string. Passing the device name directly allows percent conversions in a
DT-derived platform device name to consume nonexistent variadic arguments.

Pass the device name through a constant format so it is always handled as
data. Limit the formatted name to 31 characters to match the space
available in rproc_mem_entry::name while leaving room for its terminating
null byte.
