The V3U provides two VSPD instances, with a new update to the version
register to detect the new SoC.
Add the new version and model detection, and detail the features
available in this module.

This patch adds in the VSPd on the V3U, and successfully probes and can
read and write to registers.
However, as yet I have not been able to successfully validate the VSPD
using the UAPI interface (by forcing .uapi = true)
The observed symptoms show that the hardware halts at the first display
list queued to the device.
Notably, however the display list has been processed, and the registers
set by the display list are updated accordingly and can be read back,
inferring that the display list was processed and the frame commenced.
Alas the frame never completes, and no interrupts are generated.
Investigating this, I have seen that the CPG MSSR configures the FCPVD
and VSPD on the R8A779A0_CLK_S3D1 clock, which appears to be a 266666656
clock. This seems low, and I would expect the VSP to share the same
clocking as the VIN/VSPX, which is on R8A779A0_CLK_S1D1.
However, changing those clocks has no effect on the operation of the
VSPD.
