Rather than #define the options manually in the architecture code, add
Kconfig options for them and select them there instead.  This also allows
us to select the compat IPC version parsing automatically for platforms
using the old compat IPC interface.

Sigh, I missed to check which architecture Kconfig files actually
include the core Kconfig file. There are a few which did not. So we
broke them.

Instead of adding the includes to those, we are better off to move the
include to init/Kconfig like we did already with irqs and others.

This does not change anything for the architectures using the old
style periodic timer mode. It just solves the build wreckage there.

For those architectures which use the clock events infrastructure it
moves the include of the core Kconfig file to "General setup" which is
a way more logical place than having it at random locations specified
by the architecture specific Kconfigs.

Rather than requiring architectures that use gpiolib but don't have any
need to define anything custom to copy an asm/gpio.h provide a Kconfig
symbol which architectures must select in order to include gpio.h and
for other architectures just provide the trivial implementation directly.

This makes it much easier to do gpiolib updates and is also a step towards
making gpiolib APIs available on every architecture.

For architectures with existing boilerplate code leave a stub header in
place which warns on direct inclusion of asm/gpio.h and includes
linux/gpio.h to catch code that's doing this.  Direct inclusion of
asm/gpio.h has long been deprecated.

pointless anyway as init_task.o contains only data which is handled by
the linker script. So no point on being treated like head text.

ARCH_HAS_NMI_WATCHDOG is a macro defined by arch, but config

In order to safely work around anomaly 05000491, we have to execute IFLUSH
from L1 instruction sram.  The trouble with multi-core systems is that all
L1 sram is visible only to the active core.  So we can't just place the
functions into L1 and call it directly.  We need to setup a jump table and
place the entry point in external memory.  This will call the right func
based on the active core.

In the process, convert from the manual relocation of a small bit of code
into Core B's L1 to the more general framework we already have in place
for loading arbitrary pieces of code into L1.

We need to place icache flush funcs into L1 inst sram to work around a
hardware anomaly.  But this currently breaks SMP support as the L1 inst
sram is per-core and cannot be called directly.  So in preparation for
making that work, split the two options.

Further, split out the SMP depend so that we can allow some for SMP.

Anomaly 05000491 says that IFLUSH cannot have certain types of memory
stalls triggered before it has completed in order to function correctly.
One such condition is that it be in L1 instruction.  So add a config
option to move it there, default it to on, and throw up a warning when
it is turned off and this anomaly exists.

Since the anomaly should be worked around, we can drop the older method
of calling IFLUSH multiple times.
