[COMMON] media: smfc: add support for custom quantization tables

Some users needs to configure their own quantization tables instead of
the quality factors that is the factor to calculate the quantization
tables based on the ones suggested by ITU-81 Appendix K.1 and K.2.

Now the driver supports for the new custom control variable,
V4L2_CID_JPEG_QTABLES2 that is an array of V4L2_CTRL_TYPE_U8 with
128 values (two arrays with 64 elements). One of the table is for
the quantization table of the Luma and the other table is for the
chroma components. The values in the quantization tables should be
specified in the zig-zag scan order.

Note that once the custom quantization tables are configured, it is
used for the compressions until a new quality factor or a new
quantization is configured.
Also note that the custom quantization tables are configured to H/W
even though the table stored in the v4l2_ctrl is in transient state.
Therefore, configuring new custom quantization tables with s_ctrl or
s_ext_ctrl during the H/W is working for the current context may cause
an unpredictable result which means the quantization tables that is
used by the H/W may be incorrect and it impacts the compression
quality of the compressed stream.
