iio: proximity: isl29501: Fix return type of isl29501_register_writegrafted
isl29501_register_write() was returning a u32 instead of an int.
Since the function returns negative error codes (such as -ERANGE or
return values from i2c_smbus_write_byte_data()), returning an unsigned
integer type prevents callers from correctly checking for negative error
conditions.
Fix this by changing the function return type from u32 to int.
This was found through manual code review.
Fixes: 1c28799257bc ("iio: light: isl29501: Add support for the ISL29501 ToF sensor.")
