i2c: uniphier: use devm_get_addr() to get base address
Currently, fdtdec_get_addr_size() does not support the address translation, so it cannot handle device trees with non-straight "ranges" properties. (This would be a problem with DTS for UniPhier ARMv8 SoCs.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
