spi-nor: intel-spi: Remove useless 'buf' parameter in the HW/SW cycle
intel_spi_hw_cycle() and intel_spi_sw_cycle() don't use the parameter 'buf' at all. Remove it. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Cyrille Pitchen <cyrille.pitchen@wedev4u.fr>
