net: phy: micrel: Fix lan8814_config_init

commit bf91f4bc9c1dfba75e457e6a5f11e3cda658729a upstream.

The blamed commit introduced the function lanphy_modify_page_reg which
as name suggests it, it modifies the registers. In the same commit we
have started to use this function inside the drivers. The problem is
that in the function lan8814_config_init we passed the wrong page number
when disabling the aneg towards host side. We passed extended page number
4(LAN8814_PAGE_COMMON_REGS) instead of extended page
5(LAN8814_PAGE_PORT_REGS)
