thunderbolt: Add tb_regs.h
Every thunderbolt device consists (logically) of a switch with multiple
ports. Every port contains up to four config regions (HOPS, PORT,
SWITCH, COUNTERS) which are used to configure the device.
The tb_regs.h file contains all known registers and capabilities from
these config regions.
