[spibus] add initial placeholders for transfer mode and frequency.

This doesn't yet implement it in the controllers or the transfer
calls, but it's a start.

Obtained from: loos (frequency), ray/zrouter (transfer mode)

Add copyright statement I should have had on these files in 2006,
based on the spibus_if.m file.

Add an OFW SPI compatible bus. Fix the spibus probe to return
BUS_PROBE_GENERIC and not BUS_PROBE_SPECIFIC (0) so the OFW SPI bus can
attach when enabled. Export the spibus devclass_t and driver_t
declarations.

Replace `inline static' by `static inline'.

If I interpret the C standard correctly, the storage specifier should be
placed before the inline keyword. While at it, replace __inline by
inline in the files affected.

Fix comments.

# someone should write a bit-bang spi parallel port interface :-)
