arm64/cpufeature: Fix field sign for DIT hwcap detection
Since it was added our hwcap for DIT has specified that DIT is a signed
field but this appears to be incorrect, the two values for the enumeration
are:
0b0000 NI
0b0001 IMP
which look like a normal unsigned enumeration and the in-kernel DIT usage
added by 01ab991fc0ee ("arm64: Enable data independent timing (DIT) in the
kernel") detects the feature with an unsigned enum. Fix the hwcap to specify
the field as unsigned.
