x86/cpufeatures: Enable cpuid for Intel SHA extensions
Add Intel CPUID for Intel Secure Hash Algorithm Extensions. This feature
provides new instructions for accelerated computation of SHA-1 and SHA-256.
This allows the feature to be shown in the /proc/cpuinfo for cpus that
support it.
Refer to SHA extension programming guide in chapter 8.2 of the Intel
Architecture Instruction Set Extensions Programming reference
for definition of this feature's cpuid: CPUID.(EAX=07H, ECX=0):EBX.SHA [bit 29] = 1
