ramips: Add Xiaomi Mi Router 4A 100M International

Browse Source 
The international version of Mi Router 4A 100M is physically
identical to the non-international one, but appears to be
using a different partitioning scheme with the "overlay"
partition being 2MiB in size instead of 1MiB. This means
the following "firmware" partition starts at a different
address and the DTS needs to be adjusted for the firmware
to work.
