I don't mind at all changing these to single line if it is 
the adopted style, however I didn't file like so when looking
through the existing headers.

C89 and C99 standard requires a new line character at the end of file.
The compiler should issue a warning when the new line character 
at the end of file is missing, otherwise it is not compliant with 
the above C standards.
So I would rather add a new line where it is missing rather than 
removing it.
There is lots of header files already in arch/arm/plat-samsung where 
there is even more than one empty line at the end of file.

OK, I will just define 2 generic macros for these DMA offsets
and possibly other two for the sizes. However when the shifts are
changed in the future SoC versions we will have to go back to
separate definitions per each register and modify the driver again.

I think I could get rid of some of them. But I was not sure
whether it is better to define all available bit fields at once
or rather only those used by the current driver, and then 
re-submit what is missing.
Anyway I will try to remove as many as possible statements that 
define a single bit position with 1 and 0.
