regulator: max1586 - fix a memory leak in max1586_pmic_remove()
In max1586_pmic_probe(), we allocate memory for max1586.
In max1586_pmic_remove(), current implementation only free rdev
which is a member of struct max1586_data.
Thus, there is a small memory leak when we unload the module.
This patch fixes the memory leak by passing max1586 to i2c clientdata,
and properly kfree(max1586) in max1586_pmic_remove().
