Subject: [PATCH 2/2] clocksource/drivers/renesas-ostm: Add OSTM support for RZ/V2H(P) SoC

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

RZ/V2H(P) (R9A09G057) SoC has Generic Timer Module(a.k.a OSTM) which
needs to deassert the reset line before accessing any registers just
like the RZ/G2L SoC.

Enable the entry point for RZ/V2H(P) SoC so that we can deassert
the reset line in probe callback.

While at it use IS_ENABLED() macro instead of open coding.
