spi: sh_qspi: Make use of the 32byte FIFO The QSPI controller on RCar Gen2 has 32byte FIFO. Instead of doing the SPI transmission 1 byte at time, if there is a 32byte chunk of data to be transferred, fill the FIFO completely and then transfer the data to/from the FIFO. This increases the SPI NOR access speed significantly. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Nobuhiro Iwamatsu <nobuhiro.iwamatsu.yj@renesas.com>
