platform/x86: ISST: Add API version of the target

Browse source

User space can get the API version using IOCTL
ISST_IF_GET_PLATFORM_INFO. This information can be used to get IOCTLs
supported by the kernel driver. This version is hardcoded in the driver.

Allow the registered client to specify the supported API version. In
this way a registered client can specify a higher API version to extend
IOCTL set.
