From: Adrian Ng Ho Yin <adrianhoyin.ng at altera.com>
Add a new optional property 'snps,dev-nack-retry-cnt' to the Synopsys
DesignWare I3C master device tree binding. This property allows
configuration of the Device NACK Retry count, which determines how many
times the controller retries a transaction when a slave device responds
with NACK.
Valid values range from 0 to 3, with a default of 0
