media: i2c: tc358746: fix possible endianness issue

Browse source

Using the u64 v4l2_dbg_register.val directly can lead to unexpected
results depending on machine endianness. Fix this by using a local
variable which is assigned afterwards. Since tc358746_read() will init
the val variable to 0 we can assing it without checking the return value
first.
