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
test app was having to explicitly set the right values in its sample
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.

This KSDK flash shim driver supports the device in the FRDM K64F
platform (enabled with this commit).
WARNING: the driver disables the system interrupts for potentially
long periods of time. This is required to avoid Read-While-Write
issues since most platforms run in XIP mode.

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.

The uart_k20 serial driver incorrectly assumed that all instances of the
UART peripheral are driven by the system clock, when actually some
instances are driven by the bus clock (which usually runs at half the
system clock). This caused incorrect baud rate calculations for UART
instances driven by the bus clock (UART2-4).

Making a reference to the common work queue code should not necessarily
drag in the system workqueue, since it is possible to use a workqueue
that is not the system workqueue. This is done by moving the system
workqueue into its own code module.
Moving the system workqueue to its own code module allows removing the
NANO_WORKQUEUE and SYSTEM_WORKQUEUE kconfig options, and compiling the
common workqueue code and system workqueue all the time. They are only
linked in the final image if a reference to them exist, same as the
other kernel modules.
