tcl/board: Add Raspberry Pi 3 board
OpenOCD cannot connect to BCM2837's JTAG interface on RPi 3 board until
the reset configuration mode is set as trst_only.
According to Table 6-31 GPIO Pins Alternative Function Assignment of
Broadcom's BCM2837 ARM Peripherials datasheet [1] and Raspberry Pi's
GPIO control in config.txt document [2], only Test Reset (TRST) pin (no
System Reset, SRST) is exposed.
