[ARM] 3433/1: ARM: OMAP: 8/8 Update board files
Patch from Tony Lindgren
This patch syncs OMAP board support with linux-omap tree.
The highlights of the patch are:
- Add support for Nokia 770 by Juha Yrjola
- Add support for Samsung Apollon by Kyungmin Park
- Add support for Amstrad E3 videophone by Jonathan McDowell
- Remove board-netstar.c board support as requested by Ladislav Michl
- Do platform_device registration in board files by Komal Shah et al.
