rockchip: rk322x: update max-frequency for mmc node
mmc using 150000000 as max-frequency like what rk3288 sets. This can speed up the mmc read/write, the actual mmc clock is: Before this patch: 37.125M After this patch: 49.5M Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Acked-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com>
