nvadsp: Extend to support AON DSP

Browse Source 
- Added num_irqs to chip data structure and modified enum to
  suit the driver to both AON and ADSP
- Added num_regs to chip data and modified reg bank enum
  to suit both AON and ADSP
- Added chipdata variable to indicate if amc is not available or
  relevant
- Modified aram_exit to execute only if aram size is not null
- Avoid passing fw name for registration as it currently passing "APE"
- WFI status check logic is dsp specific. Hence separated out into
  new API
- Mapping mbx interrupts is specific to AON. Hence added platform device
  specific API to map the shared interrupts
- Avoided empty interrupt spamming for level triggered interrupts.
  This fix does no harm even for edge triggered interrupts
