Subject: [PATCH 6/6] arm64: dts: ipq8074: add VQMMC supply
SDHCI controller claims DDR, HS200 and HS400 1.8V support, however it
cannot achieve those using the 2.95V I/O that is the default set by
firmware.
Since we know have access to the PMP8074 PMIC provided LDO that provides
the I/O voltage set it as VQMMC supply so that higher speeds can actually
be achieved.
