Andy Lutomirski 090edbe23f x86/power/64: Use struct desc_ptr for the IDT in struct saved_context ...

x86_64's saved_context nonsensically used separate idt_limit and
idt_base fields and then cast &idt_limit to struct desc_ptr *.

This was correct (with -fno-strict-aliasing), but it's confusing,
served no purpose, and required #ifdeffery. Simplify this by
using struct desc_ptr directly.

No change in functionality.
