tcl/interface: add linuxgpiod cfg for Aspeed AST2600
Add linuxgpiod cfg for Aspeed AST2600 for a case if JTAG master needs
to be implemented using linuxgpiod intead of hardware JTAG master mode.
These AST2600 GPIOs will be mapped to JTAG/SWD signals.
+-----------+-------------+-------------+
| signal | GPIO name | gpio offset |
+-----------+-------------+-------------+
| TCK/SWCLK | GPIOI2 | 66 |
| TMS/SWDIO | GPIOI3 | 67 |
| TDI | GPIOI1 | 65 |
| TDO | GPIOI4 | 68 |
| nTRST | GPIOI0 | 64 |
