In commit aeb5032b3f, a dependency on IRQ_DOMAIN was added, which causes
regressions on previously working setups: a previously working non-DT
kernel configuration now loses its PMIC support. The lack of PMIC
support in turn causes the loss of other functionality the kernel had.
This dependency was added because the driver now registers its
interrupts with the IRQ domain code, presumably to prevent a build error.
The result is that OMAP3 oopses in the vp.c code (fixed by a previous
commit) due to the lack of PMIC support.
However, even with IRQ_DOMAIN enabled, the driver oopses:
Unable to handle kernel NULL pointer dereference at virtual address 00000000

This happens because we try to register an IRQ domain with a NULL ops
structure, and the first thing irq_domain_add() does is try to
dereference this ops structure.
So, fix the problem by getting rid of the incorrect OF_IRQ ifdef and
wrapping the IRQ domain bits of the driver with an IRQ_DOMAIN ifdef
instead.
