At typically 120 mA, these chips run hot even when idle; this low power mode cuts that power usage by a factor of around 100. This version provides a generic routine to poll a register until its masked value equals some value ... e.g. bit set or cleared. It's basically what the previous wait_phy_ready() did, but this version is generalized to support the handshaking needed to enter and exit low power mode.
