Since commit 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()"), platform_get_irq() will call 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.

Incorrect format (should be wo '<' and '>').
According to:
https://www.kernel.org/doc/html/latest/process/stable-kernel-rules.html
the '<' and '>' should be added when adding a # <kerner>
Also, not sure why this should be backported to stable kernel anyway.
Because false-positive error messages are bad and cause users to file false-positive bug-reports.
