greybus: spi: Restructure spi.c to share it with other bundle drivers
This patch restructures spi.c as spilib core, so that the same logic can be reused for SPI connections implemented as part of different bundle types. This is required for Firmware Management Bundle. Note that the 'struct gb_protocol' and its callback aren't moved to a separate file in this commit to make its reviews easier. That will be done by a following patch.
