ARM: tegra21: hawkeye: set modem control signal to unused for wifi sku

Hawkeye platform with WIFI SKU will not use the modem control signal
and so keeping these in low power mode.

Signals are:
	MODEM-DETECT  ---> PK4
	MODEM_AP_WAKE_MDM --->PK5
	MDM1_COLDBOOT --->PK6
	MDM1_PWR_ON --->PK7

	MDM1_MDM_RST ---->PL0
	MDM1_MDM_PWR_REPORT --->PL1
