Quentin Schulz 6a0bfbbe20 net: phy: mscc: migrate to phy_select/restore_page functions 
The Microsemi PHYs have multiple banks of registers (called pages).
Registers can only be accessed from one page, if we need a register from
another page, we need to switch the page and the registers of all other
pages are not accessible anymore.

Basically, to read register 5 from page 0, 1, 2, etc., you do the same
phy_read(phydev, 5); but you need to set the desired page beforehand.

In order to guarantee that two concurrent functions do not change the
page, we need to do some locking per page. This can be achieved with the
use of phy_select_page and phy_restore_page functions but phy_write/read
calls in-between those two functions shall be replaced by their
lock-free alternative __phy_write/read.

Let's migrate this driver to those functions.
