[ARM] 3470/1: Clear the HWCAP bits for the disabled kernel features
Patch from Catalin Marinas Glibc interprets the HWCAP bits and decides on what features to use. However, even if the features are present in the hardware, they are not always supported by the kernel and hence the corresponding bits have to be cleared from the elf_hwcap variable.
