The target seems to be working on 5.4, so drop 4.14 support in
preparation for removing it from master entirely.

-Subject: MIPS: DTS: img: marduk: switch mmc to 1 bit mode
-
-The mmc block in Pistachio allows 1 to 8 data bits to be used.
-Marduk uses 4 bits allowing the upper 4 bits to be allocated
-to the Mikrobus ports. However these bits are still connected
-internally meaning the mmc block recieves signals on all data lines
-and seems the internal HW CRC checks get corrupted by this erroneous
-data.
-
-We cannot control what data is sent on these lines because they go
-to external ports. 1 bit mode does not exhibit the issue hence the
-safe default is to use this. If a user knows that in their use case
-they will not use the upper bits then they can set to 4 bit mode in
-order to improve performance.
-
-Also make sure that the upper 4 bits don't get allocated to the mmc
-driver (the default is to assign all 8 pins) so they can be allocated
-to other drivers. Allocating all 4 despite setting 1 bit mode as this
-matches what is there in hardware.
