[POWERPC] Uninline and export virq_to_hw() for the pasemi_mac driver

Browse Source 
Uninline virq_to_hw and export it so modules can use it. The alternative
would be to export the irq_map array instead, but it's an infrequently
called function, and keeping the array unexported seems considerably
cleaner.

This is needed so that the pasemi_mac driver can be compiled as a module.
