b771721a74 net/usb/r815x: avoid to call mdio functions for runtime-suspended device
Don't replace the usb_control_msg() with usbnet_{read,write}_cmd()
which couldn't be called inside suspend/resume callback. Keep the
basic functions unlimited. Instead, using usb_autopm_get_interface()
and usb_autopm_put_interface() in r815x_mdio_{read,write}().

Use the buffers from kmalloc to replace those one.

c073f666ff net/usb: add relative mii functions for r815x
Base on cdc_ether, add the mii functions for RTL8152 and RTL8153.
The RTL8152 and RTL8153 support ECM mode which use the driver of
cdc_ether. Add the mii functions. Then, the basic PHY access is
possible.
