The "KT" serial port has another use case for a "received break" quirk,
so before adding another special case to the 8250 core take this
opportunity to push such quirks out of the core and into a uart_port op.

Stephen says:
"If the callback function is to no longer live in 8250.c itself,
 arch/arm/mach-tegra/devices.c isn't logically a good place to put it,
 and that file will be going away once we get rid of all the board files
 and move solely to device tree."

...so since 8250_pci.c houses all the quirks for pci serial devices this
quirk is similarly housed in of_serial.c.  Once the open firmware
conversion completes the infrastructure details
(include/linux/of_serial.h, and the export) can all be removed to make
this self contained to of_serial.c.

Get rid of the mdesc pointer in the fixup function call.  No one uses
the mdesc pointer, it shouldn't be modified anyway, and we can't wrap
it, so let's remove it.

Platform files found by:

  $ regexp=$(git grep -h '\.fixup.*=' arch/arm |
		sed 's!.*= *\([^,]*\),* *!\1!' | sort -u |
		tr '\n' '|' | sed 's,|$,,;s,|,\\|,g')

This adds support for the i2c busses on paz00. The 3rd bus is
reserved for the nvec, which acts as master and i2c-tegra has
not yet support for this kind of operation.
The sound codec (alc5632) is connected to the first bus and will
be added once the codec and glue driver is upstream.
The thermal sensor (atd7461) is connected to dvc as usual, but will
not be added now because i2c-tegra still misses probe support
(needs I2C_FUNC_SMBUS_EMUL).
