[PATCH RESEND v2] x86/platform: Remove Technology Systems 5500 board

[PATCH RESEND v2] x86/platform: Remove Technology Systems 5500 board

[Sean Young]

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

Thanks for pointing that out. I don't know what tree sashiko is looking
at but the ts5500 gpio and mtd maps drivers are long since gone out of
the tree, there are no dependencies on TS5500 since 7.2-rc1.

$ git grep -l TS5500
