[ Upstream commit bc9d1f0cecd2407cfb2364a7d4be2f52d1d46a9d ]
Addresses the following warning when building j2_defconfig:

arch/sh/kernel/cpu/sh2/probe.c:24:16: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
24 | j2_ccr_base = (u32 __iomem *)of_flat_dt_translate_address(node);
