tpm: move tpm 1.x selftest code from tpm-interface.c tpm1-cmd.c

Move the tpm1 selftest code functions to tpm1-cmd.c
and adjust callers to use the new function names.
 1. tpm_pcr_read_dev() to tpm1_pcr_read_dev().
 2. tpm_continue_selftest() to tpm1_continue_selftest().
 3. tpm_do_selftest() to tpm1_do_selftest()
