724282d27d k20uart: Let's use 'port' everywhere as it is more readable
Using "which" is somehow awkward to use when 'port', on the contrary, is
blatantly more readable.

d3a4177d92 pci: Provide a simpler yet powerful PCI enumeration API
This fixes many issues around PCI enumeration from old API:
- a static internal table was fed with scanning results, thus eating
  memory, and worse: due to the limit of its size, scanning for new
  classes was impossible unless growing statically the size of this
  table --> more memory eaten! Not to mention PCI enumeration is done
  once at boot time for driver initialization and that's all, so this
  table is hanging around for nothing afterwards.
- one needs first to scan a class, then maybe he will be able to find
  his device via pci_dev_find. Where all could be done at once.
- pci_dev_find was not trustworthy due again to the internal table. Now
  if the device is not found, one will know it really went through all
  the possbilities.
- still let the possibility for hard-coded BARs value on driver side
  (thus no PCI scan required). However this is greatly advised not to do
  so as BARs might change over a firmware/BIOS update.

Comparison:

old pci_dev_scan: could only filter out via class mask.
new pci_dev_scan: can filter out via a class, a vendor and device ID
(it could easily do the same for Function and BAR index as these are
usually fixed and informed through datasheet)

old pci_dev_scan: was limited in its findings by the size of the
internal result table.
new pci_dev_scan: can proceed through all the buses and devices every
time (there are optimizations to avoid useless work of course)

old results did not tell about the function or BAR index.
new one tells, and the structure has not bloated.

old internal code: was storing a big table of results
new internal code: is only storing a small lookup structure and an
array of Bus:Dev pairs for each PCI class for optimizations purpose.
(though, if needed, we could disable this through some #ifdef)

Usage:

- Have a local struct dev_info
- Fill it with what you want to look for, currently: only class and
  vendor_id/device_id. Function and BAR index could be added if needed.
- Call pci_bus_scan_init(): this will reset the internal lookup
  structure.
- Call pci_dev_scan(<a pointer to your dev_info>): at first call, the
  internal lookup structure will pick up the informations from dev_info
  and will try to find out what has been requested. It will return 1 on
  success, or 0. On 1, your dev_info structure will be updated with the
  found informations. If more devices can be found against the same
  lookup informations, just call again pci_dev_scan(<a pointer to your
  dev_info>) as long as it returns 1. When 0 is hit, it will mean you
  found all.

18fa789ca0 Rework constructor macros
Routines are no longer flagged as constructors using the FUNC_CONSTRUCT(level)
macro.  This is because some compilers do not support constructor levels.

To indicate that a routine should be a constructor, the SYS_PREKERNEL_INIT()
macro should be used AFTER the definition of the routine.  For example ...

void my_library_init(void)
{
    ...
}

SYS_PREKERNEL_INIT(my_library_init, 500);

The first parameter to SYS_PREKERNEL_INIT() is the name of the routine.  The
second is the priority level (000...999).  The lower the number, the higher
the priority.  NOTE: It is important that all three digits are specified;
otherwise the linker may put the constructors in an undesired order.

Renames the include file defining non-public microkernel structures
from k_struct.h to kernel_structures.h, and relocates it to the
microkernel's non-public include file directory. This means that
applications and drivers including the microkernel's public APIs,
using microkernel.h, can no longer access non-public information.

Note: This change also eliminates some redundant #includes by the
microkernel's own subsystems, since the inclusion of minik.h brings
in the vast majority of public and non-public APIs.

Also adds code to generate a build error if the hard-coded size

(Can't check for size equality, since the structure size may vary
from one compiler to the next. If the value is too large any extra
space in the command packet set will simply go unused.)
