Subject: [PATCH 1/5] spi: rockchip: Perform trivial code cleanups

Perform a few trivial code cleanups, to obey the reverse Christmas tree rule,
to avoid unnecessary line wrapping by using the 100-column width better, to
actually obey the 100-column width in one case, and to make the way a couple
of wrapped function arguments are indented a bit more readable.

No intended functional changes are introduced by these code cleanups.
