apalis/colibri imx6/imx6ull/imx7: defconfig: Enable fastboot support

Add fastboot support for Apalis iMX6, Colibri iMX6, Colibri iMX6ULL and
Colibri iMX7 boards. Remove CONFIG_FASTBOOT_BUF_SIZE from
colibri_imx7_emmc_defconfig to get the default value of 0x7000000 instead
of 0x10000000, to make it consistent with the other boards.
