firmware_test: Replug Ethernet programmatically

This patch adds Ethernet dongle replug during routine restoring system
from a timeout (called in cleanup). This functionality is available only
on ServoV4P1.

Additionally this patch adds methods for servo's ethernet power
management.

BUG=b:177734303
TEST=Run custom firmware FATF using ServoV4P1. Manually disable Ethernet
controller (using e.g. "ioexset EN_PP3300_ETH 0" in servo's console)
during test. Make sure replug is done during timeout routine and
Ethernet is running well after the test is finished.
