Only got a couple of relatively small notes. With them addressed, we'll be happy to merge this as this looks great!

* The value was used internally by BMD as RV_GIGADEVICE, but it does not belong to Gigadevice (SoC vendor) or to Nucleisys (processor vendor). This is visible on JTAG TAP IDCODE of DTM and RISC-V mvendorid CSR of GD32VF103 SoC.
* Proper JEP-106 value of 0xa36 belonging to Nuclei Systems Technology * 307 is related to Nuclei N307 processor core

Detailed description
Not tested as I don't have that board, only GD32VF103. But going by the logs, it makes sense:
Info : JTAG tap: gd32vw553.cpu tap/device found: 0x10307a6d (mfg: 0x536 (Nuclei System Technology Co Ltd), part: 0x0307, ver: 0x1)Info : JTAG tap: auto0.tap tap/device found: 0x790007a3 (mfg: 0x3d1 (GigaDevice Semiconductor (Beijing)), part: 0x9000, ver: 0x7)There is valuable internal cleanup w.r.t. JTAG and generic RISC-V probe paths. I can discard
gd32vw5_probe()stub, and the weak nop mechanism will simply return false for it.Your checklist for this pull request
