irqdomain: Convert __irq_domain_create() to use struct irq_domain_info

Browse Source 
The existing __irq_domain_create() use a bunch of parameters to create
an irq domain.

With the introduction of irq_domain_info structure, these parameters are
available in the information structure itself.
Using directly this information structure allows future flexibility to
add other parameters in a simple way without the need to change the
__irq_domain_create() prototype.

Convert __irq_domain_create() to use the information structure.

[ tglx: Fixup struct initializer ]
