arch, x86, irq: purge useless handler declarations from hw_irq.h
PATCH 1/1 arch, x86, irq: purge useless handler declarations from hw_irq.h
Within arch/x86/include/asm/hw_irq.h, there are some declarations for the C-level handlers called into directly from the IDT-referenced assembly stubs.
These declarations are never used as they are referenced from assembly only.
Furthermore, these declarations got their attributes wrong: there is no '__irqentry' (parameter passing via stack) attached to them.
Also, the list of declarations isn't complete: none of the tracing-capable variants is declared, for example.
Purge the handler declarations.

Tested on x86_64, compiled on i386.
