Fix an issue where, if a task is pending on a nano timeout, the duration
it wants to wait is not taken into account by the tickless idle code.
This could cause a system to wait forever, or to the limit of the timer
hardware (which is forever, for all intents and purposes).
This fix is to add one field in the nanokernel data structure for one
task to record the amount of ticks it will wait on a nano timeout. Only
one task has to be able to record this information, since, these waits
being looping busy waits, the task of highest priority is the only task
that can be actively waiting with a nano timeout. If a task of lower
priority was previously waiting, and a new task is now waiting, it means
that the wait of the original task has been interrupted, which will
cause said task to run the busy loop on the object again when it gets
scheduled, and the number of ticks it wants to wait has to be recomputed
and recorded again.

We can save a great deal of RAM this way, it only needs to be
in RAM if dynamic interrupts are in use.
At some point this config option broke, probably when static
interrupts were introduced into the system.
To induce build (instead of runtime) errors when irq_connect_dynamic()
is used without putting the table in RAM, the dynamic interrupt
functions are now conditionally compiled.

Decisions on compiler optimizations were done on the architecture level,
this does not scale and some SoCs will have different optimization levels

differently when using the same CPU which we use to set the right optimization

The interrupt API has been redesigned:
- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
It will be used in situations where the new static irq_connect()
won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
exactly the same way as its dynamic counterpart. The old static irq
macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
generated inline with irq_connect()
ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.

The code to poke the system integration module to disable clock gating
for UARTs only works for UART0-3 since all the bits are in the same
register. However, clocks for UART4 and UART5 are controlled by
another register. This means that we have been writing to the wrong
bit for enabling UART4.
This patch fixes this issue, and moves the clock gating clock into
board initialization. The incorrect code has also been removed to
prevent accidental mis-use. The dev_data struct is no longer needed
for uart_k20, so that is removed as well.
