sh: j2: Use ioremap() to translate device tree address into kernel memory



[ Upstream commit bc9d1f0cecd2407cfb2364a7d4be2f52d1d46a9d ]

Addresses the following warning when building j2_defconfig:

arch/sh/kernel/cpu/sh2/probe.c: In function 'scan_cache':
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);
      |
