The goal is to acquire the plane address by MappedFrameBuffer::maps().
Currently it returns the address of the begging of a buffer where a
plane exists.

To achieve this, it is necessary to not only change MappedFrameBuffer
implementation, but also fix codes of filling length in
FrameBuffer::Plane. It is set to the buffer length, not plane length,
in some places.

Hirokazu Honda (5):
  libcamera: mapped_framebuffer: Return plane begin address by
    MappedBuffer::maps()
  cam: file_sink: Fix wrong mapping planes
  android: camera_device: Fills the size of plane to
    FrameBuffer::Plane::length
  WIP: libcamera: V4L2VideoDevice: Fix a bug in CreateBuffer()
  WIP: android: jpeg: Use maps() and clean up
