omap4: fix boot issue on ES2.0 Panda

Browse Source 
Fix boot issue on ES2.0 Panda by tuning some
IO settings. The CONTROL_EFUSE_2 register has
to be over-ridden in software for 4430 boards.

Commit 23e9f0723e48615332119de4f4ec7a833a282628
wrongly did this for CONTROL_EFUSE_1. Reverting
this and doing it for CONTROL_EFUSE_2.
