include: Add version info to struct sbi_platform

Browse Source 
Add version control of sbi_platform structure
- Add opensbi_version, this gives information of opensbi revision on
which the sbi_platform table was created.
- Add platform_version field in sbi_platform structure for platform
level version control.
