Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Originally, x86 just supported APIC. Then later support
for the Mint Valley Interrupt Controller was added. This
controller is mostly similar to the APIC with some differences,
but was integrated in a somewhat hacked-up fashion.
Now we define irq_controller.h, which is a layer of abstraction
between the core arch code and the interrupt controller
implementation.
Contents of the API:
- Controllers with a fixed irq-to-vector mapping define
_IRQ_CONTROLLER_VECTOR_MAPPING(irq) to obtain a compile-time
map between the two.
- _irq_controller_program() notifies the interrupt controller
what vector will be used for a particular IRQ along with triggering
flags
- _irq_controller_isr_vector_get() reports the vector number of
the IRQ currently being serviced
- In assembly language domain, _irq_controller_eoi implements
EOI handling.
- Since triggering options can vary, some common defines for
triggering IRQ_TRIGGER_EDGE, IRQ_TRIGGER_LEVEL, IRQ_POLARITY_HIGH,
IRQ_POLARITY_LOW introduced.
Specific changes made:
- New Kconfig X86_FIXED_IRQ_MAPPING for those interrupt controllers
that have a fixed relationship between IRQ lines and IDT vectors.
- MVIC driver rewritten per the HAS instead of the tortuous methods
used to get it to behave like LOAPIC. We are no longer writing values
to reserved registers. Additional assertions added.
- Some cleanup in the loapic_timer driver to make the MVIC differences
clearer.
- Unused APIs removed, or folded into calling code when used just once.
- MVIC doesn't bother to write a -1 to the intList priority field since
it gets ignored anyway
