[PATCH] cadence_qspi: Refactor the flash reset functionality

[Venkatesh Yadav Abbarapu]

As the flash reset is handled in spi nor core, removing the
flash reset functionality. As the configuration like tristate
and hysterisis need to be enabled by the cdo. Handle the flash
reset only for mini u-boot case.
