spi: Fixes for v5.15

A few small fixes for v5.15, mostly driver specific but there's one in
the core which fixes a deadlock when adding devices on spi-mux that's
triggered because spi-mux is a SPI device which is itself a SPI
controller and so can instantiate devices when registered.  We were
using a global lock to protect against reusing chip selects but they're
a per controller thing so moving the lock per controller resolves that.
