sparseirq: move __weak symbols into separate compilation unit
GCC has a bug with __weak alias functions: if the functions are in
the same compilation unit as their call site, GCC can decide to
inline them - and thus rob the linker of the opportunity to override
the weak alias with the real thing.
So move all the IRQ handling related __weak symbols to kernel/irq/chip.c.
