iio: light: tcs3472: use iio helper function to guarantee direct mode

Browse source

Replace the code that guarantees the device stays in direct mode
with iio_device_claim_direct_mode() which does same.  This allows
removal of an unused lock in the device private global data.

Also prevents a previous race condition when a buffer is enabled whilst
a raw read is going on.
