eth: mpnic: add register init for the device

Browse source 
Perform one time register initialization during mpnic_probe(). These CSR
settings are either static configs that only need to be set once, or
pulses for zeroizing on chip SRAMs, which also only need to be done
once.

This initialization is idempotent and does not require any matching
deinitialization in the remove path. We can unbind and re-bind the
driver and perform the same initialization without problems.
