spi25: Introduce generic spi_prepare_io()/spi_finish_io()
Introduce two new functions to be hooked up in the chip database:
* spi_prepare_io(), and
* spi_finish_io().
These will be used to prepare multi-i/o and QPI operations. Hence,
hook them up to all the chips that support those. spi_prepare_4ba()
is wrapped to account for overlaps with 4BA support.
