I just tried to check if the read performance acutally increased when
using an 8-bit data bus. As a quick test, I use the fatload command to
read a chunk of 1 GByte from an eMMC flash (generated with dd from
Linux). However, I don't see any difference at all:

Currently, the entry "bus-width = <8>" in the ZynqMP's sdhci nodes
is not evaluated. This results in the bus width staying at its default

Fix this by calling mmc_of_parse. This function also checks for the
"no-1-8-v" and "max-frequency" entries. Remove the handling of t
