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 [-Warray-bounds] flash.c:72:13: warning: array subscript is above array bounds [-Warray-bounds] flash.c:128:13: warning: array subscript is above array bounds [-Warray-bounds] flash.c:129:13: warning: array subscript is above array bounds [-Warray-bounds] flash.c:133:12: warning: array subscript is above array bounds [-Warray-bounds] Signed-off-by: Wolfgang Denk <wd@denx.de>
