4d2fa77334 spi: Fix SPI configuration flags
SPH and SPO flags are not mutual exclusive, this way
they need to occupy different bit fields.

Added missing () around _in_ parameters of macros as well.

524a50e61e spi: Add a utility pointer for the application on SPI callback
It might be needed sometime to get some private data forwarded to the
callback, thus such user_data pointer is the easiest way to proceed.
Adding a macro to set the word size as well.

1804292f6d spi: Add an error callback type
Such type will be used in case of unrecoverable error on driver side
while transceiving.

Taking the opportunity to fix spi_transceive declaration as it should be
static.

5f353e0e94 spi: change inline functions to static inline
When compiling with optimization level 0 (-O0), the linker complains
about missing references to uart functions. This is due to compiler
treating this functions as extern, since -O0 disables function inlining,
as described in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=49653

So change the declaration to static inline.

dd12326e86 spi: Fix the generic API
- Add a spi_slave_select function for controllers supporting per-slave
  addressing
- Adding one full-duplex r/w function
- All r/w function go through one unique driver call
- Only one callback for all
