iio: temperature: ltc2983: fix u32 read into a unsigned long long

Browse Source 
Currently the read of temp using of_property_read_u32_index is reading
a u32 value into a unsigned long long.  This relies on machine endianness
to work correctly, so fix this by reading a u32 value and setting temp
to this value.

Addresses-Coverity: ("Reliance on integer endianness")
Fixes: f110f3188e ("iio: temperature: Add support for LTC2983")
