drivers/spi: Treat all stages commonly when adding drivers

Clean it up and add all flash chip drivers to postcar stage thereby.

There seem to be SPI controllers that don't need the individual
flash chip drivers. For those postcar support was added in b6b1b23
(console/flashconsole: Enable support for postcar). However for
SPI controllers that need the individual drivers (i.e. those with
CONFIG_SPI_FLASH_INCLUDE_ALL_DRIVERS=y), linking of the postcar
stage was broken.

For all other stages, the set of compilation units stays the same.
