mtd: ts5500_flash: 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.

This provides a driver for the on-board flash of the Technologic
System's TS-5500 board. The 2MB flash is split into 3 partitions
which are accessed as separate MTD devices.
mtd0 and mtd2 are the two BIOS drives, which use the resident
flash disk (RFD) flash translation layer.
mtd1 allows you to reprogram your BIOS. BE VERY CAREFUL.
Note that jumper 3 ("Write Enable Drive A") must be set
otherwise detection won't succeed.
