Kyungmin,
Maybe as you know, should be changed all universal_ functions when adding
other universal board for avoiding confusing later. And need this so that
we can support single kernel image in future. Thanks.

NOTE:
Changes since v3:
- Changed only machine name not functions based on v1 patch

Changes since v2:
- Changed machine name from 'UNIVERSAL' to 'UNIVERSAL_C210'

Changes since v1:
- Changed default UFCON tx/rx trigger level

Keep in mind. but as you see other universal patches. it's almost
static variables do don't make a problem when other universal board
comes.
Yes. some time later it needs to change the name, but current samsung
socs has each SoCs directory so it also don't make a problem.

Thank you,
Kyungmin Park

 NOTE:
 Changes since v3:
 - Changed only machine name not functions based on v1 patch

 Changes since v2:
 - Changed machine name from 'UNIVERSAL' to 'UNIVERSAL_C210'
