[PATCH v3 3/5] ARM: dts: aspeed: santabarbara: Add JTAG GPIO line names

[Fred Chen]

Label the GPIO lines used for the CPU JTAG debug interface
(TDI/TCK/TMS/TDO and CPLD DBREQ/TRST). These lines are driven from
userspace via GPIO bit-banging to emulate JTAG signals for CPU
debugging, so naming them lets userspace request the lines by name.
