JTAG pins are mapped as below. To access the JTAG pins, we need to
control the GPIO pins from SPL which seems to be the earliest stage for
JTAG.
- JTAG nTRST: GPIO36 / Input
- JTAG TDI: GPIO61 / Input
- JTAG TMS: GPIO63 / Input
- JTAG TCK: GPIO60 / Input
- JTAG TDO: GPIO44 / Output

Very few of the existing event-spy records use the arguments they are
passed. Update them to use a simple spy instead, to simplify the code.
Where an adaptor function is currently used, remove it where possible.

The main difference between StarFive VisionFive 2 1.2A and 1.3B is gmac.
You can read the PCB version of the current board by
get_pcb_revision_from_eeprom(), and then dynamically configure the
difference of gmac in spl_perform_fixups() according to different PCB
versions, so that one DT and one defconfig can support both 1.2A and
1.3B versions, which is more user-friendly.
