net: mii: Rename mii_stat1000_to_linkmode_lpa_t
Rename mii_stat1000_to_linkmode_lpa_t to
mii_stat1000_mod_linkmode_lpa_t to indicate it modifies the passed
linkmode bitmap, without clearing any other bits.
Add a helper to set/clear bits in a linkmode.
Use this helper to ensure bit are clear which the stat1000 indicates
should not be set.
Fixes: c0ec3c273677 ("net: phy: Convert u32 phydev->lp_advertising to linkmode")
