TPM_RETRY defined in

  32d33b29ba07 ("TPM: Retry SaveState command in suspend path")

has nothing to do with time. I'll also remove the comment about 5

The definitions for TPM_RETRY seem fairly arbitrary. Jason, could
tpm_i2c_nuvoton also use the same constant as tpm_tis_spi and TPM 1.2
suspend, try max 50 times instead of five?
