The following UART parameters are defined within the UART driver:

1). Whether the UART uses DMA (dma_enabled), by default set to 0
2). The size of dma buffer (set to 4096 bytes)
3). The time after which the dma should stop if no more data is received.
4). The auto suspend delay that will be passed for pm_runtime_autosuspend
    where uart will be disabled after timeout

Different UARTs may be used for different purpose such as the console,
for interfacing bluetooth chip, for interfacing to a modem chip, etc.
Therefore, it is necessary to be able to customize the above settings
for a given board on a per UART basis.

This change allows these parameters to be configured from the board file
and allows the parameters to be configured for each UART independently.

If a board does not define its own custom parameters for the UARTs, then
use the default parameters in the structure "omap_serial_default_info".
The default parameters are defined to be the same as the current settings
in the UART driver to avoid breaking the UART for any board. By default,
make all boards use the default UART parameters.

Who is the author of this patch?  The first version says Jon[1], v2 says
Deepak[2].  Either way, please ensure proper authorship is attributed
using From: at the beginning of the changelog.  (git-format-patch will
do this for you when the authorship is correct in the git history.)

Even better would be to summarize the changes since the first version
after the '---' so it would be clearer why the authorship was changed.

Only 1/3 of my comments from v3 were addressed in this version.  Please
re-read my comments there[3]. 

Kevin
