Document FCPVD found in RZ/G2L alike SoCs. FCPVD block is similar to
FCP for VSP found on R-Car SoC's . It has 3 clocks compared to 1
clock on fcpv. Introduce new compatibles renesas,r9a07g044-fcpvd
for RZ/G2{L,LC} and renesas,r9a07g054-fcpvd for RZ/V2L to handle this
difference.
The 3 clocks are shared between du, vspd and fcpvd. No driver changes
are required as generic compatible string "renesas,fcpv" will be used
as a fallback.

v4->v4 Resend:
* Rebased to next.
v3->v4:
* Added Rb tag from Rob.
v2->v3:
* Updated the compatibles by replacing items->enum as
it is just one item.
v1->v2:
* Documented RZ/{G2,V2}L FCPVD bindings
* Introduces new compatibles renesas,r9a07g0{44,54}-fcpvd
* Added clock-names property
* described clocks.
