ARM: dts: dra7xx: Increase spi-max-frequency to 76.8MHz for QSPI
According to AM572x DM SPRS953A, QSPI maximum bus speed can be 76.8MHz. Therefore, increase the spi-max-frequency value of QSPI node to 76.8MHz for DRA74 and DRA72 evm. This improves flash raw read speed by ~2MB/s. Signed-off-by: Vignesh R <vigneshr@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
