libcamera: mapped_framebuffer: Return plane begin address by MappedBuffer::maps()

Browse source 
MappedBuffer::maps() returns std::vector<MappedBuffer::Plane>.
Plane has the address, but the address points the beginning of the
buffer containing the plane.
This makes the Plane point the beginning of the plane. So
MappedBuffer::maps()[i].data() returns the address of i-th plane.
