iio: light: tsl2563: Do not hardcode interrupt trigger type
[ Upstream commit 027641b52fe37b64af61025298ce160c8b9b7a73 ]
Instead of hardcoding IRQ trigger type to IRQF_TRIGGER_RAISING,
let's respect the settings specified in the firmware description.
To be compatible with the older firmware descriptions, if trigger
type is not set up there, we'll set it to default (raising edge).
Fixes: 388be4883952 ("staging:iio: tsl2563 abi fixes and interrupt handling")
Fixes: bdab1001738f ("staging:iio:light:tsl2563 remove old style event registration.")
