#### Why I did it
Fix a bug in HFT where the asic clock was not synchronized with the
system clock, causing it to report a time around 1970.

There is a dependency between this PR and:
sonic-net/sonic-sairedis#1734
The PR to sonic-buildimage should be merged first, followed by the PR to
sonic-sairedis.

##### Work item tracking
- Microsoft ADO **(number only)**:

#### How I did it
Added phcsync script for ASIC clock synchronization on Mellanox
platforms: created phcsync.sh that syncs PTP clocks with system clock
every 60 seconds.

#### How to verify it
