Hello build bot (Jenkins),

spi_master: Introduce SPI_MASTER_4BA feature flag

Add a feature flag SPI_MASTER_4BA to `struct spi_master` that advertises
programmer-side support for 4-byte addresses in generic commands (and
read/write commands if the master uses the default implementations). Set
it for all masters that handle commands address-agnostic.

Don't prefer native 4BA instructions if the master doesn't support them.
