[PATCH] ARM: imx_v4_v5_defconfig: Fix the selection of 32 bit flash support for iMX21ADS board

[Fabio Estevam]

commit 1a96571d (Enable 32 bit flash support for iMX21ADS board) aimed to 
enable 32 bit flash support, but all it did was to delete an unset option.

Fix this by enabling CONFIG_MTD_MAP_BANK_WIDTH_4 option.

Jaccon,

I don't have a MX21ADS board handy to test it, but I guess this was the correct
intention of your patch, right?
