tpm tis: Do not print timeout messages twice
The tis driver does a tpm_get_timeouts out side of tpm_chip_register,
and tpm_get_timeouts can print a message, resulting in two prints, eg:
tpm tpm0: [Hardware Error]: Adjusting reported timeouts: A 10000->750000us B 10000->2000000us C 10000->750000us D 10000->750000us
Keep track and prevent tpm_get_timeouts from running a second time, and
clarify the purpose of the call in tpm_tis_core to only be connected to
irq testing.
