Now that we have new SPI NOR framework in place that supports 4 byte addressing mode by default, get rid of CONFIG_SPI_FLASH_BAR

I already mentioned in previous mail, BAR is not exact replacement for 4-byte. Some controllers do handle > 16MB flashes even-though controller support 3-byte addressing. we have these board since from 2014.

Better to make changes in accordance with that.

Hmm, could you point to such SPI controller drivers? I can work on adding a fallback and enable FLASH_BAR support only for such SoC/Board. We dont want to enable this support for all.
