[PATCH] arm64: imx: Handle both MMC2 and SD2 boot devices on Data Modul i.MX8M Mini eDM SBC

[Marek Vasut]

Handle both MMC2 and SD2 boot devices as SDMMC device 1 on
Data Modul i.MX8M Mini eDM SBC. In case the system boots from
a microSD card, the BootROM reports boot device as SD2_BOOT
instead of MMC2_BOOT. Continue booting from that SDMMC device
instead of falling back to SDP. Note that SDMMC device 1 is
the microSD slot on this device, SDMMC device 2 is the eMMC,
but BootROM reports the numbers the other way around, hence
the potential confusion in this commit message.
