[U-Boot] [PATCH v2 05/11] km: add CONFIG_KM_COMMON_ETH_INIT for km common eth init

[Valentin Longchamp]

This must be defined by a board support file that want to use the
keymile common.c board_eth_init function that requires ethernet_present
to be defined.

Currently all the km architectures use it but the kmp204x architecture
later supported in this series does use another board_eth_init function
and thus does not define it.

- add CONFIG_KM_COMMON_ETH_INIT for the km board that need the common.c
