UPSTREAM: dm: spi: Read default speed and mode values from DTThis patch update the behavior introduced bycommit 96907c0fe50a ("dm: spi: Read default speed and mode values from DT")In case of DT boot, don't read default speed and mode for SPI fromCONFIG_* but instead read from DT node. This will make sure that boardswith multiple SPI/QSPI controllers can be probed at differentbus frequencies and SPI modes.Remove also use in boards of the value speed=0 (no more supported)for ENV in SPI by using CONFIG_ENV_SPI_MAX_HZ=0.DT values will be always used when available (full DM support ofSPI slave with available DT node) even if speed and mode are requested;for example in splash screen support (in splash_sf_read_raw)or in SPL boot (in spl_spi_load_image).The caller of spi_get_bus_and_cs() no more need to force speed=0.But the current behavior don't change if the SPI slave is notpresent (device with generic driver is created automatically)or if platdata is used (CONFIG_OF_PLATDATA).Signed-off-by: Patrick Delaunay Acked-by: Jagan Teki Change-Id: I6f5990b73f33815a7acb9b5da9c90dce48b6211dSigned-off-by: Jon Lin (cherry picked from commit b0cc1b846fcb310c0ac2f8cbeb4ed5947dc52912) List of files: /rk3399_rockchip-uboot/configs/mscc_luton_defconfig
