am335x_evm_defconfig: Enable CONFIG_CMD_EXTENSION

am335x_evm_defconfig is used for BeagleBone Black, popular single board
computer with wide extension support. Enable CONFIG_CMD_EXTENSION by default
since extension detection is already implemented for am335x.

Also run make savedefconfig for am335x_evm_defconfig
