This fixes a problem where sx150x_regmap_reg_width() returns 8 for the data register (reg 0) for sx1504 where it should return 4, and return a correct 8 for sx1505 but for the wrong reason (both chips lack the 'advanced' register). This is not a real problem, since nothing depends on the function returning 4 or 8, and certainly not if it is returning 8 for the wrong reason. But fix this to avoid nasty surprises down the line.
