sh: Remove sh7757lcr board

This board has not been converted to CONFIG_DM by the deadline of v2020.01
and is missing other conversions which depend on this as well.  Remove it.

As this is the last SH4A board, remove that support as well.

- * SH-4A has support for unaligned 32-bit loads, and 32-bit loads only.
- * Support for 64-bit accesses are done through shifting and masking
- * relative to the endianness. Unaligned stores are not supported by the

- * struct.
- *
- * The same note as with the movli.l/movco.l pair applies here, as long
- * as the load is gauranteed to be inlined, nothing else will hook in to
- * r0 and we get the return value for free.
- *
- * NOTE: Due to the fact we require r0 encoding, care should be taken to
- * avoid mixing these heavily with other r0 consumers, such as the atomic
- * ops. Failure to adhere to this can result in the compiler running out
- * of spill registers and blowing up when building at low optimization
- * levels. See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34777.
