crypto: ccp: Handle the legacy TMR allocation when SNP is enabled
The behavior and requirement for the SEV-legacy command is altered when
the SNP firmware is in the INIT state. See SEV-SNP firmware ABI
specification for more details.
Allocate the Trusted Memory Region (TMR) as a 2MB-sized/aligned region
when SNP is enabled to satisfy new requirements for SNP. Continue
allocating a 1MB-sized region for !SNP configuration.
[ bp: Carve out TMR allocation into a helper. ]
