[PATCH] clocksource/drivers/riscv: Increase the clock_event rating

[Prabhakar]

From: Lad Prabhakar <prabhakar.mahadev-lad.rj at bp.renesas.com>

Renesas RZ/Five SoC has OSTM blocks which can be used for clock_event and
clocksource [0]. The clock_event rating for the OSTM is set 300 but
whereas the rating for riscv-timer clock_event is set to 100 due to which
the kernel is choosing OSTM for clock_event.

As riscv-timer is much more efficient than MMIO clock_event, increase the
rating to 400 so that the kernel prefers riscv-timer over the MMIO based
clock_event.

Note, Ive set the rating similar to RISC-V clocksource, on ARM architecture
the rating for clk_event is set to 450.
