cannot distinguish registers located on the same address and having different index field

[taichi-ishitani]

Cannot distinguish indirect registers below.

• located on the same address
• have different index fields

For example:

• register_0
  • offset address: 0x00
  • index field: active when bit_field_0 is 0
• register_1
  • offset address: 0x00
  • index field: active when bit_field_1 is 0

In case of above example, both register_0 and register_1 are active when both bit_field_0 and bit_field_1 are 0 and this is illegal case.
