3d4e0446af ipa: mali-c55: Convert AWB to UQ<4, 8> usage 
Utilise the new FixedPoint type to explicitly calculate gains for AWB in Q4.8
format. This ensures that reporting of gains in metadata reflect the true
AWB gains applied.

6b5ecd96ff ipa: mali-c55: Reduce AWB calculations to float precision 
The AWB calculations are determined using double precision, and then
will be soon stored in a quantized float.

Use float types for the intermediate types after the sums have been
converted to an average to remove static cast assignments.

cdc523225c libcamera: Drop remaining file names from header comment blocks 
Header comment blocks used to contain the file name. Considered as
useless information, the names have been removed, with the last ones
supposed to be dropped in commit d3bf27180e ("libcamera: Drop
remaining file names from header comment blocks"). A few have however
been forgotten, and more crept back since. Remove them.

While at it, fix one typo in a header comment block by replacing
'MaliC55 with Mali-C55', and add a missing blank line in
src/ipa/rpi/pisp/pisp.cpp.
