Jessica Clarke 6ec8bf9f3d riscv: Convert local interrupt controller to a newbus PIC 
Currently the local interrupt controller implementation is based on
pre-INTRNG arm/arm64 code, using hand-rolled event code rather than
INTRNG. This then interacts weirdly with the PLIC, and other future
interrupt controllers like the APLIC and IMSICs in the upcoming AIA
specification, since they become the root PIC despite not being the
logical root. Instead, use a real newbus device for it and register
it as the root PIC.

This also adapts the IPI code to make use of the newly-added INTRNG
generic IPI handling framework, adding a new sbi_ipi as the PIC. In
future there will be alternative devices for sending IPIs that will
register with higher priorities, such as the proposed AIA IMSIC and
ACLINT SSWI.
