tpm: work around bug in Broadcom BCM0102 chipset
Patch tpm-correct-tpm-timeouts-to-jiffies-conversion reveals a bug in the
Broadcom BCM0102 TPM chipset used in the Dell Latitude D820 - although
most of the timeouts are returned in usecs as per the spec, one is
apparently returned in msecs, which results in a too-small value leading
to a timeout when the code treats it as usecs. To prevent a regression,
we check for the known too-short value and adjust it to a value that makes
things work.
