tcl: add hi3798 target and Tocoding Poplar board config
This config covers the 4x Cortex A53 CPUs. A custom connector
is required from J14 to standard ARM JTAG on v1 boards. However
v2 hardware should have a standard FTSH-105-01-L-DV connector.
Pinmuxing code to enable JTAG pins is included in l-loader-poplar
repository, so board is flashed with open source code, JTAG
is available at very early boot. Alternatively the following
pokes can be issued from U-Boot to enable JTAG (e.g. to debug
hisilicon SDK).
