tpm: Switch to platform_get_irq_optional()
platform_get_irq() calls dev_err() on an error. As the IRQ usage in the
tpm_tis driver is optional, this is undesirable.
Specifically this leads to this new false-positive error being logged:
[ 5.135413] tpm_tis MSFT0101:00: IRQ index 0 not found
This commit switches to platform_get_irq_optional(), which does not log
an error, fixing this.
Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()"
