Subject: [PATCH 01/18] irqdomain.h: Remove extern from function declarations
'extern' is not needed for function declarations. So remove it from
irqdomain.h. Note that the declarations are now unified as some had
'extern' (all these) and some did not (like
msi_device_domain_alloc_wired()).
An upside of this change is that parameters are shifted a bit to the
left, so the whole code is now more readable.
