net: phy: mscc: timestamping and PHC support
This patch adds support for PHC and timestamping operations for the MSCC
PHY. PTP 1-step and 2-step modes are supported, over Ethernet and UDP.
To get and set the PHC time, a GPIO has to be used and changes are only
retrieved or committed when on a rising edge. The same GPIO is shared by
all PHYs, so the granularity of the lock protecting it has to be
different from the ones protecting the 1588 registers (the VSC8584 PHY
has 2 1588 blocks, and a single load/save pin).
