phy: phy-rockchip-samsung-hdptx: Enable runtime PM at PHY core level

When a new PHY is created via [devm_]phy_create(), the runtime PM for it
is not enabled unless the parent device (which creates the PHY) has its
own runtime PM already enabled.

Move the call to devm_pm_runtime_enable() before devm_phy_create() to
enable runtime PM at PHY core level.

With this change the ->power_on() and ->power_off() callbacks do not
require explicit runtime PM management anymore, since the PHY core
handles that via phy_pm_runtime_{get,put}_sync() when phy_power_on() and
phy_power_off() are invoked.

Hence drop the now unnecessary calls to pm_runtime_resume_and_get() and
pm_runtime_put() helpers.
