spi: microchip-core-qspi: Add regular transfers
Merge series from Conor Dooley <conor@kernel.org>: This is a v2 of a patchset I sent about this time last year, adding the regular transfer_one_message op to the microchip-core-qspi driver. In that v1 Mark expressed his dislike for that op, so v2 is using prepare/unprepare/transfer_one instead. The unprepare implementation still contains the 750 us delay that the driver had back in v1. I've heard a suggestion internally as to why this is needed, but it was unsubstantiated, so I still have no justification for it. I held off on sending a v2 because of a lack of explanation for the delay, but I don't wanna hold off forever for something I might never understand.
