The AD3531/AD3531R has different output operating modes from the
AD3530/AD3530R. According to the AD3531/AD3531R datasheet, the
powerdown modes are:
01: 500 Ohm output impedance
10: 3.85 kOhm output impedance
11: 16 kOhm output impedance
The driver currently uses the AD3530R modes (1k, 7.7k, 32k) for all
variants, which is incorrect for AD3531/AD3531R.
Add AD3531R-specific powerdown mode strings and assign them to the
AD3531/AD3531R chip variants.
