Several IPI providers need to know the exact number of IPIs that the architecture requires, so move the enum into the public header. This is a pure code movement with no functional change.

No functional change; IPI_MAX is still 8.

IMSIC was defining its own IMSIC_NR_IPI (= 8) which happened to match the architecture's IPI_MAX. Now that IPI_MAX is exported from riscv asm/smp.h, use the architecture constant and drop the private define. This keeps the number of multiplexed IPIs in sync with the rest of the RISC-V IPI infrastructure.

The last enumerator of this driver's firmware IPI id list is a bound for the VPU mailbox protocol, not a generic host IPI limit. Follow the existing naming in this header: IPI_VPU_INIT already carries a VPU prefix, so the terminator should match. The same convention is used by the SCP IPI enum, which ends with a prefixed SCP_IPI_MAX rather than a bare IPI_MAX. Rename IPI_MAX to IPI_VPU_MAX and update the descriptor table bounds and range checks. No functional change.
