clk: renesas: Switch to fdtdec_get_addr_size_auto_noparent() on Gen2
The fdtdec_get_addr() does not take into account values set in #address-cells
and #size-cells , but assumes them to be 1 for 32bit systems and 2 for 64bit
systems. This is true for most DTs, however there are exceptions. Switch to
fdtdec_get_addr_size_auto_noparent(), which takes the #address/size-cells
values into consideration, otherwise the reset controller node register
offset is incorrectly parsed.
