[PATCHv3 2/3] mmc: dw_mmc-pltm: Remove Rockchip's custom dw_mmc driver structure

[<dinguyen@altera.com>]

From: Dinh Nguyen <dinguyen@altera.com>

Rockchip's implementation of the dw_mmc controller only requires the setting
of the SDMMC_CMD_USE_HOLD_REG on every command. With the patch to set the
SDMMC_CMD_USE_HOLD_REG by checking the slot's speed mode, this Rockchip
custom driver structure is no longer necessary.
