    e1000e: Enable GPT clock before sending message to CSME

    On corporate (CSME) ADL systems, the Ethernet Controller may stop working
    ("HW unit hang") after exiting from the s0ix state. The reason is that
    CSME misses the message sent by the host. Enabling the dynamic GPT clock
    solves this problem. This clock is cleared upon HW initialization.

    Fixes: 3e55d231716e ("e1000e: Add handshake with the CSME to support S0ix")
