[PATCH v3 11/15] ARM: dts: dra7-evm: Add wilink8 wlan support

[Kishon Vijay Abraham I]

From: Hari Nagalla 

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.

IODelay data credits to :  Vishal Mahaveer 
and Sekhar Nori
