SD<->EMMC 通道转换

PATH:ARCH/ARM/CPU/ARMV*//.H
添加函数如下：

static int emmc_lion_setup_iomux_sdhc(void)
{
	
	/* Set iomux PADS for USDHC */

	writel(SIUL2_USDHC_PAD_CTRL_CLK, SIUL2_MSCRn(150));
	writel(0x3, SIUL2_MSCRn(902));

	/* PK7 pad: uSDHC CMD */
	writel(SIUL2_USDHC_PAD_CTRL_CMD, SIUL2_MSCRn(151));
	writel(0x3, SIUL2_MSCRn(901));

	/* PK8 pad: uSDHC DAT0 */
	writel(SIUL2_USDHC_PAD_CTRL_DAT0_3, SIUL2_MSCRn(152));
	writel(0x3, SIUL2_MSCRn(903));

	/* PK9 pad: uSDHC DAT1 */
	writel(SIUL2_USDHC_PAD_CTRL_DAT0_3, SIUL2_MSCRn(153));
	writel(0x3, SIUL2_MSCRn(904));

	/* PK10 pad: uSDHC DAT2 */
	writel(SIUL2_USDHC_PAD_CTRL_DAT0_3, SIUL2_MSCRn(154));
	writel(0x3, SIUL2_MSCRn(905));

	/* PK11 pad: uSDHC DAT3 */
	writel(SIUL2_USDHC_PAD_CTRL_DAT0_3, SIUL2_MSCRn(155));
	writel(0x3, SIUL2_MSCRn(906));

	/* PK15 pad: uSDHC DAT4 */
	writel(SIUL2_USDHC_PAD_CTRL_DAT4_7, SIUL2_MSCRn(159));
	writel(0x3, SIUL2_MSCRn(907));

	/* PL0 pad: uSDHC DAT5 */
