opencv: disable broken Intel FP16 detection
With opencv-3.2, the configuration detects if the target supports
half-precision floating-point format. This fails to compile for some
Intel targets such as skylake with an error such as:
error: '_mm_cvtph_ps' was not declared in this scope
The configuration used to work in opencv-3.1 so revert two commits to
drop the FP16 detection even though it may make opencv slower.
The only change in the configure log is:
- FP16: Compiler support is available
+ FP16: Compiler support is not available
The patch should be dropped when a newer version of opencv that includes commit:
https://github.com/opencv/opencv/commit/e5d9b608c47d54e43496041595025fa282fa9de5
is available. Backporting that fix was complicated.
