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.
