Merge series "spi: Various Cleanups" from Uwe Kleine-König <u.kleine-koenig@pengutronix.de>:

Hello,

while trying to understand how the spi framework makes use of the core
device driver stuff (to fix a deadlock) I found these simplifications
and improvements.

They are build-tested with allmodconfig on arm64, m68k, powerpc, riscv,
s390, sparc64 and x86_64.

Best regards
Uwe
