[SRU][Bionic/raspi2][PATCH] UBUNTU: [Config] Remove upstream mmc modules

[Adam Smith]

The test case says to check dmesg for errors -
http://iso.qa.ubuntu.com/qatracker/milestones/384/builds/170472/testcases/1464/results
.  There is an error message, therefore it fails the test case.

I'm not proposing to switch drivers.  I'm proposing to remove the
conflicting drivers that shouldn't be in use.  If people want to use
the upstream mmc drivers for some particular reason then they can use
the generic kernels with uboot/uefi/grub2.

I honestly don't see the problem. I've built the kernel with the
patch.  It still works.  Surely it is better to fix this before
release?
