kernel: drop patch adding hardcoded kernel compilation flags
1. KCFLAGS should be used for custom flags
2. Optimization flags are arch / SoC specific
3. -fno-reorder-blocks may *worsen* network performace on some SoCs
4. Usage of flags was *reversed* since 5.4 and noone reported that
If we really need custom flags then CONFIG_KERNEL_CFLAGS should get
default value adjusted properly (per target).
