Add the SD/eMMC gate clocks and expose them for use by DT. While at it, also explose FCLK_DIV2 since this is one of the input clocks to the mux internal to each of the SD/eMMC blocks. Signed-off-by: Kevin Hilman <khilman@baylibre.com>
my Meson8b / GXBB DWMAC glue series needs this as well. This worked fine during my tests, so: Tested-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
