Add the NewVision NV3051D panel as found on the Anbernic RG353P and
RG353V. The underlying LCD panel itself is unknown (the NV3051D is
the controller), so the device name is used for the panel with a
fallback to the driver IC.

Changes from V2:
 - Ensured dt_binding_check and dtbs_check successfully passed.
 - Corrected some minor formatting issues in documentation.
 - Added another mode per userspace request for 100hz. I was unable
   to find a supported 50hz mode that would also work, so for now
   only 60hz, 100hz, and 120hz are supported.

Changes from V1:
 - Changed compatible string to the driver IC.
 - Updated documentation to use new compatible string with board
   name.
 - Refactored somewhat to make it easier to support other LCD panels
   with this kernel module.
 - Added support for 60hz mode. Adjusted pixel clock to ensure proper
   60hz and 120hz (previously was running at 124hz).
 - Added vendor prefix for NewVision. Anbernic vendor prefix added in
   https://lore.kernel.org/linux-devicetree/[e-mail]
