Cortex-M85: Remove excess eunmerators in IRQn_Type (#1533)
Values added past `Interrupt9_IRQn` are a potential problem for users
that decide to include the header, and then define device-specific
exceptions in a different enum. In this scenario a "redeclaration of
enumerator 'TIMER0_IRQn'" will occur.
Remove the excess enumerators to avoid potential issues, and to align
`IRQn_Type` with Device Header Files for other Cortex-M cores.
