tpm: move tpm1_pcr_extend to tpm1-cmd.c
Move tpm1_pcr_extend to tpm1-cmd.c and remove
unused pcrextend_header structure and
EXTEND_PCR_RESULT_SIZE and EXTEND_PCR_RESULT_BODY_SIZE
defines.
Fixes warning:
drivers/char/tpm/tpm-interface.c:609:38: warning: ‘pcrextend_header’ defined but not used [-Wunused-const-variable=]
static const struct tpm_input_header pcrextend_header = {
