phy: core: Remove unused phy_pm_runtime_(allow|forbid)

Browse source 
phy_pm_runtime_allow() and phy_pm_runtime_forbid() were added in 2013
as part of
commit ff76496347 ("drivers: phy: add generic PHY framework")
but have remained unused.

Remove them.
Fix up the (English) docs - I've left the Chinese translation.

It should also be noted that phy_power_on and phy_power_off performs
phy_pm_runtime_get_sync and phy_pm_runtime_put respectively.
There are exported APIs like phy_pm_runtime_get, phy_pm_runtime_get_sync,
phy_pm_runtime_put, phy_pm_runtime_put_sync, phy_pm_runtime_allow and
