eab9123589 nios2: fix nano_cpu_idle() 
Interrupts must always be unlocked when coming out of this function
or execution will never leave _power_save() once entered.

45cff183a2 nios2: implement nano_cpu_idle and nano_cpu_atomic_idle 
Nios II does not have a power saving instruction, so there is nothing
to really do here other than ensure that interrupts are in the correct
state when leaving nano_cpu_atomic_idle().

9433895954 nios2: basic build, non-functional 
Basic build framework for Nios2. Everything is stubbed out,
we just want to have a build going so that we can start to
parallelize implementation tasks.

This patch is not intended to be functional, but should be
able to produce a binary for all the nanokernel-based
sanity checks.
