[PATCH] tpm: display message when using gpio-reset instead of when missing it

[Tim Harvey]

Instead of displaying what looks like an error message if a
gpio-reset dt prop is missing for a TPM dipslay a more
informative message about resetting the TPM if the gpio is found:

before:
tpm_tis_spi_probe: missing reset GPIO

after:
tpm at 0: performing 1ms reset on gpio at 30210000:12

Note that the reset dt binding prop used in this driver is not
dt-compliant; it does not exist in the Linux dt-bindings documentation
and the reset is not done by the Linux driver.
