A single patch here that doesn't fit into the ARM32 series of improvements,
but fixes the same problem that affects the ARM32 boards too.

The LM90 temperature sensor should use edge-triggered interrupt because
LM90 hardware doesn't deassert interrupt line until temperature is back
to normal state, which results in interrupt storm. Correct the interrupt
trigger type.
