drivers: i2c: max32: fix i2c_configure to return 0 on success

[ubieda]

Description

Enforce i2c_configure API return value so it complies with its definition (zero on success). This was caught by running i2c_ram test.

Testing

• Setup

  • MAX32655 FTHR wired to a I2C FRAM (e.g: Adafruit's MB85RC256 breakout board: https://www.digikey.com/short/njtzwq2f)

• Build command

west build -b max32655fthr/max32655/m4 tests/drivers/i2c/i2c_ram/

• Overlay (boards/max32655fthr_max32655_m4.overlay)

/ {
	aliases {
		i2c-ram = &i2c2;
	};
};

• Console Output
