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.
