Update spi drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.

Same deal as in commit 677f1e6 ("config: Turn pointless/confusing
'menuconfig's into 'config's"), for a newly-introduced stuff.
Also clean up headers to be consistent with recent cleanups.
