RSPIF not supported

[mcuxmx]

I use "internal_kvstore_with_spif.json" as the bootloader configuration file. Then change
"target.components_add": ["SPIF"],
for
"target.components_add": ["RSPIF"],
I found out that SPIFReducedBlockDevice.cpp was not compiled, and there was a link error.

log:

Hi @mcuxmx is this driver compiling with normal Mbed OS build? Note that the bootloader is baremetal build, so it needs to mention explicitly all the components needed, so you might need to add rspif also as a new component.
