[bugfix]: crypto: ccp: Fix the issue of TDM support detection failure on Hygon platforms without psp firmware support

Before using the TDM feature, a probe command is sent to the PSP to
confirm its support status.

However, when the psp firmware is not loaded, the probe command cannot
be supported, so it should be set to an unsupported state.
