[Crash-utility] ppc: work out irq and fix pte translation display

> - Support "irq" command for recent kernel
>   The ppc's "irq" could not work well for recent kernel at all
>   because ppc_init() always made SIZE(irq_desc_t) invalid by itself.
>   And also, "irq" options were not supported entirely.

> Stash legacy ppc_dump_irq() behind generic_dump_irq() so that

> - Fix PTE translation for book3e
>   Although book3e uses multiple PTE bits for one attribute,
>   ppc_translate_pte() can not handle such attributes well.
>   And further privilege (kernel) RW protection bit assign of book3e
>   are different from user's ones.

> Fix and add these translation features in ppc_translate_pte().

Queued for crash-6.0.8 -- which I will try to release tomorrow (6/30).
