We have a board where measurements indicate that the current three
options - leaving IO_IMPEDANCE_CTRL at the reset value (which is
factory calibrated to a value corresponding to approximately 50 ohms)
or using one of the two boolean properties to set it to the min/max
value - are too coarse.

This series adds a device tree binding for an nvmem cell which can be
populated during production with a suitable value calibrated for each
board, and corresponding support in the driver. The second patch adds
a trivial phy wrapper for dev_err_probe(), used in the third.

v2: Improve commit message for patch 1; add Rob's R-b to patch 1. No
changes in the patches themselves.

Since Dan Murphy's email address bounces, cc'ing two other @ti.com
addresses that have touched the driver in recent years.
