Arm Cortex A8 is vulnerable to variants 1 & 2 (https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability )
Part number is 0xc08 (https://developer.arm.com/docs/ddi0344/b/system-control-coprocessor/system-control-coprocessorregisters/c0-main-id-register )
False negative reported by @V10lator in #206
* ARM Cortex A12 Vulnerable to 1&2
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability
* A76 vulnerable to variant 4
All arch 8 cortex A57-A76 are vulnerable to variant 4.
https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability
* Whitelist variant4 nonvuln Arms
* ARM Cortex Whitelist & Cumulative Blacklist
Applies all information about vulnerabilities of ARM Cortex processors (from https://developer.arm.com/support/arm-security-updates/speculative-processor-vulnerability ).
Whitelist & blacklist approach, using both vulnerable and non vulnerable status for each identified CPU, with vulnerabilities tracked cumulatively for multi CPU systems.

Variant 4 - Add function to 'whitelist' the hand-full of CPUs unaffected by speculative store bypass.
This would allow improved determination of variant 4 status ( #189 ) of immune CPUs while waiting for the 4.17/stable patches to be backported to distro kernels.

* amd families fix
amd families are reported by parse_cpu_details() in decimal
* remove duplicates
Only list processors which speculate and are immune to variant 4.
Avoids duplication with non-speculating CPUs listed in is_cpu_specex_free()

* ibrs can't be enabled on no ibrs cpu
If the cpu is identified, and does not support SPEC_CTRL or IBRS, then ibrs can't be enabled, even if supported by the kernel.
