tpm: ftpm_tee: remove incorrect of_match_ptr annotation

Building with W=1 shows a warning about of_ftpm_tee_ids being unused when
CONFIG_OF is disabled:

    drivers/char/tpm/tpm_ftpm_tee.c:356:34: error: unused variable 'of_ftpm_tee_ids' [-Werror,-Wunused-const-variable]

Drop the unnecessary of_match_ptr().
