thermal: intel: int340x: Allow limited thermal MSI support

On some Lunar Lake pre-production systems, not all the MSI thermal
vectors are valid. In that case instead of failing module load, continue
with partial thermal interrupt support.

pci_alloc_irq_vectors() can return less than expected maximum vectors.
In that case call devm_request_threaded_irq() only for current maximum
vectors.
