ARM: dts: dra7-evm: Add wilink8 wlan support
The wilink module is a combo wireless connectivity sdio
card based on Texas Instrument's wl18xx solution. It is a
4-wire, 1.8V, embedded sdio wlan device with an external
irq line and is power-controlled by a gpio-based fixed
regulator.
Add pinmux configuration and IODelay values for MMC4.
On dra7-evm, MMC4 is used for connecting to wilink module.
