[U-Boot] [PATCH V2] OMAP3: Various: Update serial platdata to update reg_offset to 0

V1 I changed all the platform data to explicitly name the entries
instead of just using a table of numbers. This would hopefully
address future proofing against the header changing order. I
copy-pasted the table from my board to a series of boards and then
later realized I had accidentally changed the UART number which would
have broken a few boards.
V2, Fixes that issue because igep, overo, beagle and devkit8000 used
UART3 instead of UART1, so it was a correction on my part. The change
from V1 was kept, but the correct UART was referenced.
