[PATCH v2 0/3] spi: cadence_qspi: clock enable, compatible, write protect

1) enable the clock(s) before accessing the QSPI registers
2) add RZ/N1 specific compatible string
3) add an option to enable hardware write protection
   (TBD: maybe drop this change)

Both have been split from "Renesas RZ/N1 additional drivers" series.
