powerpc: Abstract H_CEDE calls into a sleep functions
This consolidates several implementations, and it no longer leaves
MSR[EE] enabled after the decrementer interrupt is handled, but
rather disables it on return.
The handler no longer allows a continuous ticking, but rather dec
has to be re-armed and EE re-enabled (e.g., via H_CEDE hcall) each
time.

lib/powerpc: Add generic decrementer exception handler
Add the lib/powerpc/handlers.c file and associated header files as a place
to implement generic exception handler functions for inclusion in tests.
Add a generic exception handler for a decrementer (0x900) interrupt which
will reset the decrementer to its maximum value.
