Impact: cleanup, no functionality changed

ia32_setup_rt_frame() has a duplicated code block labelled
"Make -mregparm=3 work" for setting up the register parameters
to the user-mode signal handler.

This is harmless but ugly. Remove the redundant assignments.

Add essential system devices, including GPIO controllers, automatically
at core_initcall time. This ensures that the devices are there when the
PIO driver gets initialized at postcore_initcall, fixing a bug exposed
by commit d6634db8 "avr32: Use
platform_driver_probe for pio platform driver".

Those inline assembly segments using the umlal instruction must have
the & modifier so to be sure that a purely input register won't alias
one of the registers used as input+output.  In most cases, the inputs
are still used after the outputs are touched, and most binutil versions
insist on "rdhi, rdlo and rm must all be different" even for ARMv6+.

Canonicalize a few remaining header guards, with the exception for

Drop double underscores from header guards in arch/x86/include.  They
are used inconsistently, and are not necessary.
Signed-off-by: NH. Peter Anvin <hpa@zytor.com>

Change header guards named "ASM_X86__*" to "_ASM_X86_*" since:

a. the double underscore is ugly and pointless.
b. no leading underscore violates namespace constraints.

a) the only difference between sigcontext and sysdep/sigcontext
is that the former contains externs for two long-dead functions.
Removed, switched the only user to sysdep/sigcontext

b) asm/sigcontext.h is removable - that of underlying architecture
would get used.
