tcl/board: Add Raspberry Pi 4 model B board
OpenOCD cannot connect to BCM2711's JTAG interface on RPi 4B board until
the reset configuration mode is set as trst_only.
According to Table 94. GPIO Pins Alternative Function Assignment of
Broadcom's BCM2711 ARM Peripherals datasheet [1] and Raspberry Pi's GPIO
control in config.txt document [2], only Test Reset (TRST) pin (no
System Reset, SRST) is exposed.
