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.

smp: Dynamically allocate the stoppcbs array
This avoids bloating the kernel image when MAXCPU is large.
A follow-up patch for kgdb and other kernel debuggers is needed since
the stoppcbs symbol is now a pointer. Bump __FreeBSD_version so that
debuggers can use osreldate to figure out how to handle stoppcbs.

Add support for symmetric multiprocessing (SMP).
Tested on Spike simulator with 2 and 16 cores (tlb enabled),
so set MAXCPU to 16 at this time.
This uses FDT data to get information about CPUs
(code based on arm64 mp_machdep).
Invalidate entire TLB cache as it is the only way yet.
