configs: remove remnants of CONFIG_SYS_NAND_QUIET_TEST

configs: remove remnants of CONFIG_SYS_NAND_QUIET_TEST

The config option has been removed by one of the syncs with the Linux
mainline MTD subsystem:
ff94bc40af (mtd, ubi, ubifs: resync with Linux-3.14)
It has been left inside the config files. Currently does not look to
serve any purpose, so remove it now from all the configs.
