Subject: iio: light: ltr501 Fix interchanged als/ps register field

From: Franziska Naepelt <[email protected]>

commit 7cc3bff4efe6164a0c8163331c8aa55454799f42 upstream.

The register mapping for the IIO driver for the Liteon Light and Proximity sensor LTR501 interrupt mode is interchanged (ALS/PS).
There is a register called INTERRUPT register (address 0x8F) Bit 0 represents PS measurement trigger.
Bit 1 represents ALS measurement trigger.
This two bit fields are interchanged within the driver.
see datasheet page 24:
