We'd like to drop this file. Can you instead please add
CONFIG_SPL_DM_SEQ_ALIAS as a new Kconfig. There is only one place in
the code (device.c) that you need to change. I think for now it should
default to n, but you could enable it for your board? I'm not sure of
the size impact of enabling it by default.

Simon
