phy: Use _nodev naming convention if non-device clients

Clients that are requesting some of uclass API's
without a device (with ofnode) usually have _nodev
naming convention.

- clk_get_by_index_nodev
- clk_get_by_name_nodev
- reset_get_by_index_nodev
- gpio_request_by_name_nodev

So, update the same naming convention PHY framework.

This doesn't change the existing functionality.
