The Exynos prepare_command function is only checking when to set the
SDMMC_CMD_USE_HOLD_REG bit. Now that there is a generic way to check
on when to set SDMMC_CMD_USE_HOLD_REG bit.

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.

This patch will enable the SDMMC_CMD_USE_HOLD_REG bit when the slot is
operating all timing modes, except for SDR50, DDR50, SDR104, and MMC_HS200.
According to the Synopsys databook :"To meet the relatively high Input Hold
Time requirement for SDR12, SDR25, and other MMC speed

Hi,
This is v3 of the patch series that makes the setting of the
SDMMC_CMD_USE_HOLD_REG
bit generic.
v3 differences:
* Read the IHR(Implement HOLD Register) bit in the HCON register. Will not use
the SDMMC_CMD_USE_HOLD_REG if the IHR bit is 0 and cclk_in_drv = 0.
* Changes

The current dw_mmc code does not do any check for this bit in the HCON
register. But I'll add the check in v3:

Hi Dinh,
I known there is IMPLEMENT_HOLD_REG[22] at HCON register.
It didn't affect with this register?
