iio: dac: ad5758: Reject out-of-range raw values
ad5758_write_raw() passes the value from userspace straight to
ad5758_spi_reg_write(), which keeps only the low 16 bits. Writing -1
to the raw attribute gives full-scale output, and 65536 gives code 0.
Return -EINVAL for values outside 0 to U16_MAX, as ad5755 does.
Fixes: 28d1a7ac2a0d ("iio: dac: Add AD5758 support")
