Subject: [PATCH 23.11] net/ice/base: fix preparing PHY for timesync command

From: Tomasz Wakula <tomaszx.wakula@intel.com>

When preparing a port for timesync command SW should provide Rx type,
which indicates the type for the Rx metadata in the ONPI interface.
According to the documentation, Rx type should always equal 0x18.

Fixes: 97f4f78bbd9f ("net/ice/base: add functions for device clock control")
