This commit was intended to allow support for 256 cards with any number
of partitions:
commit a26eba614afff0e39594101bcb73014a9a22fb33
Author: Ben Hutchings <ben@decadent.org.uk>

mmc: block: Increase max_devices
I don't think the new patch is sufficient or necessary to increase the
limit further.
Do you have a compatibility requirement to retain the numbering of the
first 7 partitions?
Ben.
