4BA: Allow disabling 4-byte address mode for SPI flash
This allows us to support flash chips in any of the following
configurations, regardless of whether the chip powers up in 3-byte or
4-byte address mode.
- standard commands with extended address register (*_4ba_ereg) or
direct commands (*_4ba_direct) in 3-byte address mode (.set_4ba =
spi_exit_4ba_*)
- standard commands (*_4ba) or direct commands (*_4ba_direct) in
4-byte address mode (.set_4ba = spi_enter_4ba_*)
- direct commands (*_4ba_direct) in either address mode (.set_4ba =
NULL)
