board/etx094/flash.c: Fix flash initialization

The ETX094 has only one NOR flash bank.  Remove all code trying to
deal with a second bank.  This also fixes a number of GCC 4.6 build
warnings:
flash.c: In function 'flash_init':
flash.c:68:13: warning: array subscript is above array bounds
[-Warray-bounds]
flash.c:70:13: warning: array subscript is above array bounds

flash.c:72:13: warning: array subscript is above array bounds
