ipq806x: 5.15: drop arm override compile patch
Drop arm override compile patch. The use is dubious and at times (2016) it was never explained why this was required. Krait CPU and Cortex-a15 may be similar but they have some intrinsic difference. While very similar they differ a lot in additional feature and also cache configuration. Also these conflict with raid6 libraty compilation that use specific workaround not compatible with cortex-a15 and produce compilation warning. Fix compilation warning: cc1: error: switch '-mcpu=cortex-a15' conflicts with switch '-march=armv7-a+simd' [-Werror] cc1: all warnings being treated as errors Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
