[net-next,v2] r8153_ecm: avoid to be prior to r8152 driver

Avoid r8153_ecm is compiled as built-in, if r8152 driver is compiled
as modules. Otherwise, the r8153_ecm would be used, even though the
device is supported by r8152 driver.

Fixes: c1aedf015ebd ("net/usb/r8153_ecm: support ECM mode for RTL8153")

v2:
Use a separate Kconfig entry for r8153_ecm with proper dependencies.
