Subject: net/mlx5e: Change 1PPS out scheme

From: Eugenia Emantayev <[email protected]>

[ Upstream commit 4272f9b88db9223216cdf87314f570f6d81295b4 ]

In order to fix the drift in 1PPS out need to adjust the next pulse. On each 1PPS out falling edge driver gets the event, then the event handler adjusts the next pulse starting time.

Fixes ee7f12205abc ('net/mlx5e: Implement 1PPS support')
