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

Browse Source 
Since commit 8b793a92d8 ("x86/cpu: Remove M486/M486SX/ELAN support"),
this board is no longer supported. Remove the mtd map too.

to use the flash chips on it, say 'Y'.

** The single, 16 megabyte flash bank is divided into four virtual

** store the kernel image loaded by the bootstrap loader. The second

** 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
** recoverable afterwards.
