ARM: dts: rockchip: set dw_mmc max-freq 150Mhz
All of mmc controllers include SDMMC, SDIO0, SDIO1, and EMMC on RK3288 are limited to 150Mhz. It was mainly caused by two reasons: - RK3288's IO pad(except DDR IO pad) is generic, which can only support the max of 150Mhz. - Mmc controller was designed at 150Mhz, and the pressure test by IC team was based on this freequency point.
