drivers: add support for the TI VLYNQ bus

Add support for the TI VLYNQ high-speed, serial and packetized bus.

This bus allows external devices to be connected to the System-on-Chip and
appear in the main system memory just like any memory mapped peripheral.
It is widely used in TI's networking and multimedia SoC, including the AR7
SoC.
