spi: Merge spi_controller.{slave,target}_abort()

Browse Source 
[ Upstream commit 6c6871cdae ]

Mixing SPI slave/target handlers and SPI slave/target controllers using
legacy and modern naming does not work well: there are now two different
callbacks for aborting a slave/target operation, of which only one is
populated, while spi_{slave,target}_abort() check and use only one,
which may be the unpopulated one.

Fix this by merging the slave/target abort callbacks into a single
callback using a union, like is already done for the slave/target flags.

Fixes: b8d3b056a7 ("spi: introduce new helpers with using modern naming")
