arm64: cpufeature: Add helpers for extracting unsigned values
The cpuid_feature_extract_field() extracts the feature value as a signed integer. This could be problematic for features whose values are unsigned. e.g, ID_AA64DFR0_EL1:BRPs. Add an unsigned variant for the unsigned fields. Cc: Ard Biesheuvel <ard.biesheuvel@linaro.org> Reported-by: NAKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: NSuzuki K.
