Adam Ford 2f6ed3b89a ARM: Various: Future-proof serial platdata 
A few boards still use ns16550_platdata structures, but assume the structure
is going to be in a specific order. By explicitly naming each entry,
this should also help 'future-proof' in the event the structure changes.

Tested on the Logic PD Torpedo + Wireless.

I only changed a handful of devices that used the same syntax as the Logic
board.  Appologies if I missed one or stepped on toes.  Thanks to Derald Woods
and Alexander Graf.

V6: Add fix to arch/arm/cpu/armv7/am33xx/board.c

V5: Add fix to arch/arm/cpu/arm926ejs/lpc32xx/devices.c

V4: Fix subject heading

V3: Remove  reg_offset out in all the structs. It was reverted out, and and if
it did exist, it would get initialized to 0 by default.

V2: I hastily copy-pasted the boards without looking at the UART number.
This addresses 3 boards that use UART3 and not UART1.
