spi: Move SPI related things into new chipdrivers/spi.h
A few things that rely heavily on `flash.h` are moved there instead:
* function signatures containing `erasefunc_t`,
* the inline default_wrsr_target() that needs to know struct flashctx.
This allows to keep the new header file free of a transitive `flash.h`
include.
