Log Message:
Reduce code duplication when setting up the interrupt handler data
structures:
- alpha_shared_intr_alloc() no longer takes a "string length" argument,
  and just uses kmem_asprintf() to create an "irq %u" string by default.
  This is suitable for nearly every caller.
- Add a alpha_shared_intr_set_string() that allows callers to override
  the default IRQ description string.
- Related: make alpha_shared_intr_string() return a const char *, since
  no callers should need to modify the string directly now.
- Re-factor PCI shared interrupt structure allocation / initialization
  into a new alpha_pci_intr_alloc(), which is suitable for nearly every
  Alpha PCI platform.  Callers are expected to first have initialized
  the interrupt hardware to the quiescent state.

Adjust various call sites of above functions to account for changes,
even if they are not able to use the newly re-factored code.
