[PATCH 5/5] irqchip/imsic: Use IPI_MAX instead of IMSIC_NR_IPI

[Guo Ren]

From: "GUO Ren (XuanTie)" <guoren at kernel.org>

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.
