Subject: [PATCH v3 0/5] Support Nuvoton NPCM Video Capture/Encode Engine

This patch series add DTS node, dt-bindings document and drivers for Video
Capture/Differentiation Engine (VCD) and Encoding Compression Engine (ECE)
present on Nuvoton NPCM SoCs.

VCD can capture/differentiate video data from digital or analog sources,
then the ECE will compress the data into HEXTILE format.

HEXTILE compressed format is defined in Remote Framebuffer Protocol (RFC
6143) and is used by VNC features, so we also add a patch to support it.

Changes since v1:
  - Add Hextile document and locate with vendor formats.
  - Add video driver entry in MAINTAINERS
  - Change config name to CONFIG_VIDEO_NPCM_VCD_ECE
  - Reduce the waiting time after resetting the VCD/ECE module
  - Correct data types of some variables
