nvic: Implement v8M changes to fixed priority exceptions
In v7M, the fixed-priority exceptions are:
Reset: -3
NMI: -2
HardFault: -1
In v8M, this changes because Secure HardFault may need
to be prioritised above NMI:
Reset: -4
Secure HardFault if AIRCR.BFHFNMINS == 1: -3
NMI: -2
Secure HardFault if AIRCR.BFHFNMINS == 0: -1
NonSecure HardFault: -1
Make these changes, including support for changing the
priority of Secure HardFault as AIRCR.BFHFNMINS changes.
