regulators: Enhance additional error data capture

Enhance the additional error data capture support to allow the same
register to be captured multiple times.

The additional error data is stored as key/value pairs. The key format
is normally:

<deviceID>_register_<register>

For example, "vdd1_register_0x7A".

If the same register is captured multiple times, a counter is appended
to make the key unique. For example, "vdd1_register_0x7A_2".

One use case for capturing the same register multiple times is when a
voltage regulator produces multiple rails. It may be necessary to do
the following:
* Set the PMBus PAGE to 0
* Capture a register for the first rail
* Set the PMBus PAGE to 1
* Capture the same register again for the second rail
