net: stmmac: dwmac4: ensure LPIATE is cleared

Browse source

LPIATE enables the hardware timer for entering LPI mode. To sure that
the correct mode is used, clear LPIATE when using manual/software-timed
mode to prevent the hardware using the timer.

stmmac_main.c avoids this being a problem at the moment by calling
stmmac_set_eee_lpi_timer(..., 0) before switching to software mode.

We no longer need to call stmmac_set_eee_lpi_timer(..., 0) when
disabling EEE as stmmac_reset_eee_mode() will now clear all LPI
settings.
