[PATCH net] net: phy: realtek: Replace phy functions with non-locked version in rtl8211e_config_init()

[Kunihiko Hayashi]

After calling phy_select_page() and until calling phy_restore_page(),
the mutex 'mdio_lock' is already locked, so the driver should use
non-locked version of phy functions. Or there will be a deadlock with
'mdio_lock'.

This replaces phy functions called from rtl8211e_config_init() to avoid
the deadlock issue.

Fixes: f81dadbcf7fd ("net: phy: realtek: Add rtl8211e rx/tx delays config")
