net: phy: aquantia: call aqr_gen3_config_init() for AQR112 and AQR412(C)

The AQrate Gen3 PHYs are AQR111(C), AQR112(C), and their multi-port
variants, like AQR411(C), AQR412(C).

Currently, AQR112, AQR412 and AQR412C are Gen3 PHYs supported by the
driver which have no config_init() implementation. I have hardware and
documentation that confirms they are compatible with the operations done
in aqr_gen2_config_init(), a Gen2-level function.

This is needed as a preparation for reading cached registers in
aqr_gen2_read_status(), which is a function that these PHYs already call.
The initial reading is done from:

aqr_gen2_config_init()
-> aqr_gen2_fill_interface_modes()
   -> aqr_gen2_read_global_syscfg()

thus the need for them to also call aqr_gen2_config_init(), in order for
the cached register values to be available.

In expectation of Gen3-specific features, introduce aqr_gen3_config_init()
which calls aqr_gen2_config_init(). Also modify the AQR111 silicon
variants to call their generation-appropriate init function. No
functional change for these, hence the minor mention.
