media: dt-bindings: Add Imagination E5010 JPEG Encoder

Add dt-bindings for Imagination E5010 JPEG Encoder [1] which is implemented
as stateful V4L2 M2M driver.

The device supports baseline encoding with two different quantization
tables and compression ratio as demanded.

Minimum resolution supported is 64x64 and Maximum resolution supported is
8192x8192.

+description: |
+  The E5010 is a JPEG encoder from Imagination Technologies implemented on
+  TI's AM62A SoC. It is capable of real time encoding of YUV420 and YUV422
+  inputs to JPEG and M-JPEG. It supports baseline JPEG Encoding up to
+  8Kx8K resolution.
