x86/geode/net5501: Add platform driver for Soekris Engineering net5501

Add platform driver for the Soekris Engineering net5501 single-board
computer.  Probes well-known locations in ROM for BIOS signature
to confirm correct platform.  Registers 1 LED and 1 GPIO-based
button (typically used for soft reset).
