As it's not always obvious what PSP bootloader or TEE version are
present in OEM systems, add the ability to get this information from
sysfs for supported platforms.

Mario Limonciello 50c4decc1b crypto: ccp - Export PSP security bits to userspace 
The PSP sets several pre-defined bits in the capabilities
register to indicate that security attributes of the platform.

Export these attributes into userspace for administrators to
confirm platform is properly locked down.
