net/mlx5: Decouple PHC .adjtime and .adjphase implementations

Browse source

[ Upstream commit fd64fd13c4 ]

When running a phase adjustment operation, the free running clock should
not be modified at all. The phase control keyword is intended to trigger an
internal servo on the device that will converge to the provided delta. A
free running counter cannot implement phase adjustment.
