Describe build with OpenSBI fw_dynamic.bin path as OPENSBI=<path> on the
same line instead of as an export. Also remedy a typo which had the wrong
directory path before the filename.

OrangePi RV is a board that uses the same EEPROM product serial identifier
as the StarFive VisionFive 2 1.3b.

In fact it is not completely compatible with the StarFive VisionFive 2
1.3b for use with Linux Kernel however it is good enough for use with
U-Boot SPL and U-Boot Main. Describe how to set the devicetree search path
and, for advanced users, suggest that it is possible to update the EEPROM
data with an invented "XOPIRV" identifier for automatic board detection.

Updates to the JH7110 common description:
- add detailed overview of JH-7110 SoC and boot process
- revise descriptions of deprecated StarFive loader modes
- refresh build directions grouped with SPL debug advice
- reduce usage instructions into common methods shared by supported boards
- cite starfive_visionfive2 board maintainer description of StarFive loader
- cite published datasheets for ambient operating temperature data

Redundant/deprecated sections of each board doc are dropped accordingly:
- deepcomputing fml13v01
- milk-v mars
- pine64 star64 (also add inclusion of JH7110 common description)
- visionfive2
