[Bug 2121690] [NEW] Add support for RISC-V StarFive VisionFive 2 Lite

[Heinrich Schuchardt]

Public bug reported:

[ Impact ]

The StarFive VisionFive 2 Lite is a new RISC-V development board based
on a JH7710S CPU.

We want to enable this board in Ubuntu 24.04.

The required changes in U-Boot are mostly on the device-tree side. There
is a minor addition in the PCI driver to allow for an enablement GPIO.

None of the JH7710 based devices is supporting RVA23. So this change
does not require a feature freeze exception for release 25.10.

[ Test Plan ]

Test booting on all supported JH7710 and JH7710S based devices.

* Milk-V Mars
* StarFive Vision Five 2
* StarFive Vision Five 2 Lite
* Pine64 Star64
* DeepComputing FML13V01

In U-Boot check

* reading from SD-card, eMMC and from NVMe (where applicable)
* networking (DHCP, tftp)

[ Where problems could occur ]

The device-tree changes might lead to boot failures on other JH7110
based devices.
