IPQ5332 firmware supports only fixed QMI firmware memory.
Hence, add support to read reserved fixed memory region from
device-tree and provide the reserved memory segments for
firmware to use during QMI firmware memory request.
Note that the ability to set the fixed memory will be introduced in
a subsequent patch. Currently, the flag remains unset by default,
ensuring that existing chipsets are unaffected.
