Previously, the OSTM driver's platform probe path was only enabled for
selected SoCs (e.g., RZ/G2L and RZ/V2H) due to issues on RZ/Ax (ARM32)
SoCs, which encountered IRQ conflicts like:
/soc/timer@e803b000: used for clock events
genirq: Flags mismatch irq 16. 00215201 (timer@e803c000) vs. 00215201 (timer@e803c000)
Failed to request irq 16 for /soc/timer@e803c000
renesas_ostm e803c000.timer: probe with driver renesas_ostm failed with error -16
These issues have since been resolved by commit 37385c0772a4
("clocksource/drivers/renesas-ostm: Avoid reprobe after successful early
probe"), which prevents reprobe on successfully initialized early timers.
With this fix in place, there is no longer a need to restrict platform
probing based on SoC-specific configs. This change unconditionally enables
reprobe support for all SoCs, simplifying the logic and avoiding the need
to update the configuration for every new Renesas SoC with OSTM.
RZ/A1 and RZ/A2 remain unaffected with this change.

v2->v3:
- Dropped config check and unconditionally enabled reprobe support for all
SoCs.
- Dropped Reviewed-by tag from Geert
v1->v2:
- Instead of adding config for new SoC, changed the probe condition to
`CONFIG_ARM64`.
- Updated commit message
- Added a Reviewed-by tag from Geert.
