Subject: [PATCH 4/5] net: phy: realtek: change order of calls in C22
read_status()
Always call rtlgen_read_status() first, so genphy_read_status() which
is called by it clears bits in case auto-negotiation has not completed.
Also clear 10GBT link-partner advertisement bits in case auto-negotiation
is disabled or has not completed.
