em(4): Add support for Comet Lake Mobile Platform, update shared code

This change introduces Comet Lake Mobile Platform support in the e1000
driver along with shared code patches described below.

- Cast return value of e1000_ltr2ns() to higher type to avoid overflow
- Remove useless statement of assigning act_offset
- Add initialization of identification LED
- Fix flow control setup after connected standby:
  After connected standby the driver blocks resets during
  "AdapterStart" and skips flow control setup. This change adds
  condition in e1000_setup_link_ich8lan() to always setup flow control
  and to setup physical interface only when there is no need to block
  resets.
