[PATCH 6/6] ARM: dts: omap4-droid4: Configure modem for serdev-ngsm

[Tony Lindgren <tony@atomide.com>]

Let's enable the TS 27.010 /dev/gsmmux* interfaces via Linux n_gsm that
can be used for voice calls and SMS with commands using a custom Motorola
format.

And let's also enable the kernel GNSS driver via serdev-ngsm that uses a
dedicated TS 27.010 channel.

Note that voice call audio mixer is not supported yet.
