configs/ls1046ardb_*: disable CONFIG_SPI_FLASH_USE_4K_SECTORS

With this setting enabled, the on-board QSPI cannot be
properly flashed. There are no error messages, but the simple
write / read / compare tests fail.

This is already disabled in the qspi and tfa defconfigs for the
LS1046ARDB platform.
