thermal/of: Assume polling-delay(-passive) 0 when absent

Browse Source 
[ Upstream commit 488164006a281986d95abbc4b26e340c19c4c85b ]

Currently, thermal zones associated with providers that have interrupts
for signaling hot/critical trips are required to set a polling-delay
of 0 to indicate no polling. This feels a bit backwards.

Change the code such that "no polling delay" also means "no polling".
