Move the line disciplines towards a conventional ->ops arrangement. For
the moment the actual 'tty_ldisc' struct in the tty is kept as part of
the tty struct but this can then be changed if it turns out that when it
all settles down we want to refcount ldiscs separately to the tty.
Pull the ldisc code out of /proc and put it with our ldisc code.

Avoid dumping garbage to the serial port when the tty is flushed. This

Serial drivers using DMA (like the atmel_serial driver) tend to get very
confused when the xmit buffer is flushed and nobody told them. They
also tend to spew a lot of garbage since the DMA engine keeps running
after the buffer is flushed and possibly refilled with unrelated data.
This patch adds a new flush_buffer operation to the uart_ops struct,
along with a call to it from uart_flush_buffer() right after the xmit
buffer has been cleared. The driver can implement this in order to
syncronize its internal DMA state with the xmit buffer when the buffer
is flushed.

The bus_shift parameter in platform_data is not needed
as we can tell the driver with the IOMEM_RESOURCE whether
the ASIC is located on a 16bit or 32bit memory bus.
The htc-egpio driver uses a more descriptive bus_width parameter,
but for drivers where the register map size fixed, we don't even
need this.

The build error is caused by the ages old gcc bug where gcc at the time of
analyzing the constraints is unable to figure out that an "i" constraint
actually can be satisfied and thus will abort unless an "r" is added to
the constraint. For the actual code generation gcc will only ever use the
"i" constraint.

Currently, saa7134 is dependent of ir-kbd-i2c, since it uses a symbol that is

sense on keeping it defined there (or on ir-commons).
So, let's move it to saa7134 and remove one symbol for being exported.
