Refactor internals of IPM driver removing bitfields and byte access of
32 bit registers.
Signed-off-by: Andrei Emeltchenko <andrei.emeltchenko@intel.com>
The current method of accessing 32-bit data and control registers does
not work for all quark architectures. Sometimes writing to those
registers byte-by-byte results in last byte occupying whole 32 bit
register.

Semantics of ENOENT error as used previously is "named entity not
found", whereas for "I/O handle is not valid", there's EBADF. For
example, POSIX/SUSV2 doesn't even list ENOENT as a possible error
for accept(), connect(), recv(), etc. whereas it lists EBADF, e.g.:

The kernel tracks time slice usage with the _time_slice_elapsed global.
Every time the timer interrupt goes off and the timer driver calls
_nano_sys_clock_tick_announce() with the elapsed time, this is added to
_time_slice_elapsed. If it exceeds the total time slice, the thread is
moved to the back of the queue for that priority level and
_time_slice_elapsed is reset to zero.
In a non-tickless kernel, this is the only time _time_slice_elapsed is
reset. If a thread uses up a partial time slice, and then cooperatively
switches to another thread, the next thread will inherit the remaining
time slice, causing it not to be able to run as long as it ought to.
There does exist code to properly reset the elapsed count, but it was
only compiled in a tickless kernel. Now it is built any time
CONFIG_TIMESLICING is enabled.

The STM32F413ZH has 1536kB of Flash and 320kB of SRAM. This
configuration is currently not supported by ST MPU driver, so fill in
the blanks.
Note: The MPU does not support region size that is not a power-of-2 (see
the SIZE field in the MPU_RASR register). This is a problem for our
1536kB Flash region, so it was rounded up to the nearest choice. This is
possible because the memory in the range 0x0818000 - 0x0FFFFFFF is
"Reserved" and thus not mapped anyway.

Instead of NULL terminated buffer arrays, let's add a parameter for each
that tells the number of spi_buf in it.
It adds a little bit more complexity in driver's side (spi_context.h)
but not on user side (bufer one has to take care of providing the NULL
pointer at the end of the array, now he requires to give the count).
This will saves a significant amount of bytes in more complex setup than
the current dumb spi driver sample.
Fix and Use size_t everywhere (spi_context.h was using u32_t).
