[2/2] ARM: tegra: DTS: cardhu: register UARTC

Commit Message

UARTC is used for the interfacing with bluetooth device.
Register this UART channel as high speed serial channel
so that it can use the APB DMA for data transfer.

The driver file got applied in Greg KH's tty tree.
Tested in linux-next 20121229 with some more changes as
linux-next-20130116 is crashing in pincontrol.
