Adds initial support for the BL702 series of chips, BL702, BL704 and BL706.
No flash bank support yet.
File name bl702.tcl was chosen over bl70x.tcl, because Bouffalo Lab
uses bl702 to mark the whole series in many of their tools.
The ndmreset bit in the RISC-V Debug Module isn't implemented correctly,
so it doesn't trigger a system reset as it should.
To solve this problem, the software reset is implemented
in the reset-assert-pre hook, which uses best reset method I could find.
What is not reset is the GLB core, which handles GPIOs, pinmux, etc.
The reset mechanism has been extensively tested, and works correctly
for both "reset run" and "reset halt", which the latter
halts very early in the BootROM.
