Fixup `SMCCC_ARCH_FEATURES` semantics
When querying `SMCCC_ARCH_WORKAROUND_1` through `SMCCC_ARCH_FEATURES`,
return either:
* -1 to indicate the PE on which `SMCCC_ARCH_FEATURES` is called
requires firmware mitigation for CVE-2017-5715 but the mitigation
is not compiled in.
* 0 to indicate that firmware mitigation is required, or
* 1 to indicate that no firmware mitigation is required.
This patch complies with v1.2 of the firmware interfaces
specification (ARM DEN 0070A).
