====================
add support for impedance control for TI dp83867 phy and fix 2nd ethernet on dra72 rev C evm

Add support for configurable impedance control for TI dp83867
phy via devicetree. More documentation in [1].
CPSW second ethernet is not working, fix it by enabling
impedance configuration on the phy.

Verified the patch on DRA72 Rev C evm, logs at [2]. Also pushed
a branch [3] for others to test.

Changes from v3:
* Fixup change log text and no code changes.

Changes from v2:
* Fixed a typo in dts and driver.

Changes from initial version:
* As per Sekhar's comment, instead of passing impedance values,
  change to max and min impedance from DT
* Adopted phy_read_mmd_indirect() to cunnrent implementation.
* Corrected the phy delay timings to the optimal value.
