Since lower-numbered thread priorities are higher, the code can be
misleading when comparing priorities, and often require the same type of
comments. Instead, use utility inline functions that does the
comparisons.
_is_prio_higher already existed, but add comparisons for "lower than",
"higher than or equal to" and "lower than or equal to".

A race condition would happend if a FIRQ interrupted a
return-from-interrupt from a RIRQ at the wrong moment: if a decision was
already taken which thread to context switch in and the FIRQ woke up
another thread of higher priority, the ready queue would be corrupted.
The solution is to lock interrupts at the moment the interrupt return
code starts looking at the kernel queues. Interrupts do not need to be
unlocked before exiting: the return-from-interrupt (rtie) instruction
will restore the correct interrupt locking state for the thread being
context switched in.

Add type cast to prevent overflow.
In the pwm driver function pwm_qmsi_get_cycles_per_sec(),
there is a multiplication which takes ticks_per_us (32 bit
unsigned integer) and USEC_PER_SEC. Practically, overflow
will not happen, since the sys clock is not that high. But,
it can trigger an overflow alarm by automatic tools.

Add delay to wait for new configuration to take effect before
returning to API caller. It takes time for any change to rtc
configuration to take effect since rtc runs under a much slower
clock.
Of course, we do not have an equation for best wait time.
The value is based on the test results on arduino 101, minfield
and quark se c1000 devboard(some margin added).

The SPI_0_CS_GPIO and SPI_0_CS_GPIO_PIN values were defaulting to
something not very usable, because of which e.g. the file system

configuration. Having a proper defaults in the board defconfig means
this isn't needed anymore.

An implementation to flush multiple d-cache lines has been added
per the top-level cache.h API. ZEP-1153 was opened to express
the need for MORE i-cache and d-cache APIs. For example, the current
cache.h API doesn't provide a means to invalidate d-cache lines
and has nothing for i-cache.
I've also modified some of the i-cache related aux registers to have
better names so that they won't be confused with d-cache.
These changes are for
ZEP-1176.

WARNING: the driver disables the system interrupts for potentially

To avoid conflicts with the definition of "FPU" by the external
cmsis sub-system, the symbol "FPU_LEGACY" is now used to denote
the FPU task group. (That is, the group of tasks that utilize
the CPU's floating point registers.)
Backwards compatibility impacts:
* Microkernel applications that define private tasks using the
DEFINE_TASK() macro must now use "FPU_LEGACY" to indicate
that the task is part of the FPU task group, rather than "FPU".
* Applications that perform operations on the members of the
FPU task group must now use "FPU_LEGACY", rather than "FPU".
(Note: There is no apparent reason for an application to
perform such an operation, so this is unlikely to impact
existing applications.)
Backwards compatibility non-impacts:
* Application MDEFs can continue to specify "FPU" when defining
a public task that is part of the FPU task group.
* Applications written for the unified kernel are unaffected,
since the kernel implements task groups differently.
