arm64: dts: meson: fix mmc v2 chips max frequencies
According the datasheets, emmc v2 chips (gxbb and gxl) don't support more that 100Mhz in UHS-1 SD modes and HS in SDIO. Align the max-frequency to 100MHz for UHS-1 and 50MHz for HS Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
