clocksource/drivers/renesas-ostm: Add support for RZ/V2L SoC

The OSTM block is identical on Renesas RZ/G2L and RZ/V2L SoC's, so instead
of adding dependency for each SoC's add dependency on ARCH_RZG2L. The
ARCH_RZG2L config option is already selected by ARCH_R9A07G044 and
ARCH_R9A07G054.

With the above change OSTM will be enabled on RZ/V2L SoC.
