f770fcb368 Add shared PCI support and enhance pc386 to support non-legacy PCI configuration space 
This patch fundamentally results from enhancements to the pc386 BSP
to support systems which do **NOT** have the legacy PCI BIOS. The
patch adds support for detecting when legacy PCI BIOS is not
present and then using IO space to access to PCI Configuration Space.
This resulted in dynamically selected between two implementations
of PCI and refactoring out the shared methods.

This patch adds shared implementations of pci_bus_count() and
pci_find_device(). Subsequent patches will remove implementations
of these methods in other BSPs where possible.

12c9dc8ff5 pc386: Eliminate pcibios.h and begin removal obsolete PCI BIOS API uses 
This first step eliminates the following as public APIs for the pc386
BSP:

  + pcib_conf_read8
  + pcib_conf_read16
  + pcib_conf_read32
  + pcib_conf_write8
  + pcib_conf_write16
  + pcib_conf_write32

The if_fxp.c driver uses these enough where I provided local macros
to allow the code to be mostly unmodified. On other architectures
these names have been used privately. It will take multiple patches
to completely eliminate these symbols from the RTEMS source tree.

The focus of the first effort is just to eliminate these as a public
pc386 API so support can be added for systems without legacy PCI BIOS.

3f5e0961b4 smdk2410: Resurrect missing gp32 files 
When the gp32 BSP was obsoleted and removed, files were deleted that
were actually used by the gp32.

This was actually a violation of the expected directory structure
and why it wasn't caught. Another example of why continuous integration
testing -- even just building is important.

8c5c53f478 am335x irq handling improvement 
This patch makes the following changes to the Beaglebone IRQ handling code:

- Disable support for nested interrupts.
- Detect spurious IRQs using the SPURIOUSIRQ field of the INTC_SIR_IRQ register.
- Acknowledge spurious IRQs by setting the NewIRQAgr bit of the INTC_CONTROL
  register. This cleans the SPURIOUSIRQ field and allows new interrupts
  to be generated.
- Improve the get_mir_reg function a bit.

Closes #2580.
