Revert "android: camera_device: Configure one stream for identical stream requests"

Browse source 
Commit d165f7da34 ("android: camera_device: Configure one stream for
identical stream requests") introduced the ability to generate through
post-processing YUV streams of identical size and format.

However the change didn't fully take into account the situation
where only mapped streams are contained in the request submitted by
the camera service to the HAL. In this case the Request will be queued
with no buffers and refused by the Camera.

Even if this seems a corner case it causes a few CTS to fail, and more
problematically it triggers out-of-order completion of requests, causing
the camera service to abort.

ERROR Camera camera.cpp:1031 Request contains no buffers
ERROR HAL camera_device.cpp:1109 '\_SB_.PCI0.I2C2.CAM0': Out-of-order completion for request 0x00007a1f1800ccd0
ERROR cros_camera_service[15706:15711]: [camera_device_adapter.cc(744)] (15711) Notify(): Fatal device error; aborting the camera service

Revert the commit until a proper solution is implemented.
