Patrik Tesarik 066007590f mb/up/squared: Fix eMMC speed for UP2 with EDK2
Since commit 402fe20e (mb/up/squared: Add mainboard) the UP2's eMMC
maximum host speed was reduced to DDR50, because HS200 showed I/O errors
in the host kernel. We found out that with EDK2 master the correct
Host Speed could not be set properly during EDK2 platform init.
Therefore eMMC would not show up for boot device selection.

This commit sets the eMMC MaxHostSpeed to the designed max value of the
used eMMC on the UP2 board and furthermore drops the override from the
ramstage.c. It's already set in the devicetree.cb.

Though CRC errors are still visible in EDK II debug logs, no other
negative effects have been observed.
