mtd: netsc520: Remove mapping since board is no longer supported

Since commit 8b793a92d862 ("x86/cpu: Remove M486/M486SX/ELAN support"),
this board is no longer supported. Remove the mtd map too.

-** partition is 14.5 MiB and is intended for the flash file system
-** image.  The last partition is 512 KiB and contains another copy
-** of the BIOS image and the reset vector.

-** Only the third partition should be mounted.  The first partition
-** should not be mounted, but it can erased and written to using the
-** MTD character routines.  The second and fourth partitions should
-** not be touched - it is possible to corrupt the BIOS image by
-** mounting these partitions, and potentially the board will not be
