Raman Gopalan 0967eb4c24 avr32dev1: Fix compilation and nsh boot-up
I recently imported NuttX version 6.0 (and nsh) into a Microchip
Studio project [1] on Windows to figure out what was going wrong with
the avr32dev1 build. I also briefly checked NuttX version 10.

I worked with the assumption that the avr32 (avr32dev1) specific
changes to the codebase were minimal across NuttX releases.

For the initial proof of concept I used Microchip Studio version 7.0
(with the recent Microchip's ASF updates). I use avr32-gcc (4.4.7)
hosted here [2] for building NuttX for avr32dev1 on GNU/Linux.

Even with the Microchip Studio project, I had initial debug problems
with just stepping through the code a line at a time. I had to bring
in crt0, a trampoline stub and the linker file from one of my older
projects to really build on the suspicion I had with the linker file.

Perhaps an older version of avr32-gcc did something differently. I am
not sure about this. I used avr32-objdump to see the output sections
of the generated elf file. I just had to tweak the linker script to
ensure correct linking of the sections.

With those changes, I was able to inspect the UART sections within
NuttX Microchip Studio project.

Second important change: the transmit pin: I had to reassign the pin
to see the nsh console.

These are the currently assigned UART pins:

RX: PA_24 -> Physical IC pin 59
TX: PB_02 -> Physical IC pin 24

For the avr32dev1 board, they are pins: J1 (berg pin 28) and J2 (berg
pin 10).

In addition, the PR fixes silly compilation problems with avr32dev1.

I have tested the nsh build with my avr32dev1 boards. I used Atmel ICE
to program one of them (flash at 0x80000000) and dfu-programmer to
test my other board (flash at 0x80002000). The other RS-232 parameters
are the same as they were.
