Current design:

This is just the one of the users of the SPI flash API, but not the only one.
spi_flash.h

Proposed one (may be):
Suppose If we have one more qspi controller(zynq) which is connected to serial nor
cmd_sf.c ----------- spi_flash.h --------------- SF-NOR

Did the formating here go awry ?
But anyway, your sf_probe.c/sf_ops.c/sf.c will only need to somehow discern whether to call the regular SPI API or SPI-NOR API functions.
