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

From: Adam Smith <blondesaluki at gmail.com>

BugLink: https://bugs.launchpad.net/bugs/1762835

The Bionic Linux-raspi2 kernel has both the upstream and downstream pi
mmc modules enabled. Running the latest server image users can see
this error in dmesg:

Error: Driver 'sdhost-bcm2835' is already registered, aborting...

Due to this error the pi server image is failing a testcase on the iso
tracker.  It is also not clear to users what mmc modules are in use.

The attached patch removes the upstream mmc modules from the kernel config.

 - Adjusted context.
 - Kept CONFIG_MMC_SDHCI_IPROC=m to match rpi-4.19.y.]
