Let's add minimal support for droid 4 with MMC and WLAN working. It can be booted with appended dtb using kexec to a state where MMC and WLAN work with currently no support for it's PMIC or display. Note that we are currently using fixed regulators as we don't have support for it's cpcap PMIC. I'll be posting regmap_spi based minimal cpcap patches later on for USB and the debug UART on droid 4 multiplexed with the USB connector.
