Several IP versions duplicate code and can't use the common helpers.
Move this code into a single function so that the helpers can be used.

psp_v10_0_init_microcode used to get securedisplay_context unconditionally and now this is restricted to RENOIR following the logic in psp v12. Better is to fetch all FW details unconditionally and make the size_bytes to 0 (just to be sure) in specific PSP versions to prevent their load.
