xen/pm_idle: Make pm_idle call default_idle

cpuidle: replace xen access to x86 pm_idle and default_idle
..scribble on pm_idle and access default_idle,
have it simply disable_cpuidle() so acpi_idle will not load and
architecture default HLT will be used.
idea was to have one call - disable_cpuidle() which would make
pm_idle not be molested by other code. Sadly it falls short of
that and only dissallows cpuidle_idle_call and acpi_idle_call to
not set pm_idle (which is good!). The amd_e400_idle and mwait_idle
can still setup pm_idle which we really do not want.
So lets make pm_idle be stuck to default_idle and that will
thwart other generic code to overriding it.
