[PATCH 0/2] qcom: dts: qrb4210-rb2 usb/emmc fixes

[Caleb Connolly <caleb.connolly@linaro.org>]

Add the missing iommus property on the first sdhc, and set a default
mode for USB role switch. The iommus property in particular is necessary
when running U-Boot as a first-stage bootloader, since it can't rely on
EDK2 to configure the SMMU and crashes with:

[020b9ed0d]TLB Dump Message:Not a valid memory address to dump TLBs for device APPS_TCU or no memory available.
[020b9f533]SMMU GLOBAL TCU NON-SEC FAULT: bit mask=0x00002000
[020b9fb23]SMMU:>> APPS_TCU NonSec Global Fault:
[020b9ff9f] NSGFSR=0x80000002
[020ba0404] NSGFAR=0x00000000bf6c6800
[020ba0909] NSGFSYNR0=0x00000000
[020ba0d1b] NSGFSYNR1=0x00c000c0
[020ba117d] NSGFSYNR2=0x00000000
[020ba15a9] NSCR0=0x00200406

The GFSYNR1 register in particular clues us in to the stream ID of the
peripherals, in this case 0x00c0 corresponds to the first SDHC.
