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.")

+
+description: >
+  The Aspeed BMC SoC supports DDR3 and DDR4 memory with and without ECC (error
+  correction check).
+
+  The memory controller supports SECDED (single bit error correction, double bit
+  error detection) and single bit error auto scrubbing by reserving 8 bits for
+  every 64 bit word (effectively reducing available memory to 8/9).
+
+  Note, the bootloader must configure ECC mode in the memory controller.
