AMD southbridge: remove sp5100

Southbridge SP5100 support was compiled with SB700 code, but static
device info structure would use sp5100/chip.h. To solve this drop
support for separate chip sp5100 and adjust the relevant Kconfig
options.

Removes chip directory:
  src/southbridge/amd/sp5100/

Rename Kconfig option
 from: SOUTHBRIDGE_AMD_SP5100
   to: SOUTHBRIDGE_AMD_SUBTYPE_SP5100
