Sowjanya Komatineni	6a8a8b5170	spi: tegra210-quad: Add support for hardware dummy cycles transfer ... Tegra Quad SPI controller hardware supports sending dummy bytes based on programmed dummy clock cycles after the actual transfer bytes. This patch adds this support of hardware dummy bytes transfer and skips transfer of dummy bytes from the software. For dummy cycles more than Tegra Quad SPI hardware maximum dummy cycles limit, driver transfers dummy bytes from the software.
