net: phy: smsc: add proper reset flags for LAN8710A

Browse Source 
[ Upstream commit 57ec5a8735dc5dccd1ee68afdb1114956a3fce0d ]

According to the LAN8710A datasheet (Rev. B, section 3.8.5.1), a hardware
reset is required after power-on, and the reference clock (REF_CLK) must be
established before asserting reset.
