v2 - remove the patch that modified 8250_of.c to keep it from
     registering before this driver when this driver was deferred
     as it was getting it's "clocks". This was fixed by changing
     the Device Tree entry to remove "clock-frequency". This results
     in both drivers getting "clocks" and getting same deferral.

Add UART driver for the new Broadcom 8250 based STB UART. The new
UART is backward compatible with the standard 8250, but has some
additional features. The new features include a high accuracy baud
rate clock system and DMA support.
