[coreboot-gerrit] Change in coreboot[master]: drivers/spi/tpm: Poll TPM_VALID bit until valid

[Shelley Chen (Code Review)]

Hello build bot (Jenkins), 

I'd like you to reexamine a change. Please visit

    https://review.coreboot.org/22370

to look at the new patch set (#2).

Change subject: drivers/spi/tpm: Poll TPM_VALID bit until valid

drivers/spi/tpm: Poll TPM_VALID bit until valid

In case the TPM is doing a long crypto operation the initial probe
could be very delayed.  Rather than end up in recovery make the delay
long enough to accommodate the (current) long crypto times.
