[U-Boot] [PATCH 1/3] spl: imx6: Let spl_boot_device return USDHC1 or USDHC2

[sbabic at denx.de <sbabic@denx.de>]

> Currently, when the spl_boot_device checks the boot device, it
> will only return MMC1 when it's either sd or eMMC regardless
> of whether or not it's MMC1 or MMC2.  This is a problem when
> booting from MMC2 if MMC isn't being manually configured like in
> the DM_SPL case with SPL_OF_CONTROL.
> This patch will check the register and return either MMC1 or MMC2.

Applied to u-boot-imx, master, thanks !
