generic: backport BLOCK OF support patch
Backport BLOCK OF support patch merged upstream and refresh pending
BLOCK patches.

This is a new way to declare partition table for BLOCK device (eMMC
currently supported) with the use of DTS.

Current pending patch are adapted to not cause regression with current
downstream implementation of a similar functionality.

Also enable the new OF_PARTITION config by default.

Subject: [PATCH 8/9] mmc: block: set fwnode of disk devices
Set fwnode of disk devices to 'block', 'boot0' and 'boot1' subnodes of
the mmc-card. This is done in preparation for having the eMMC act as
NVMEM provider.
