regulator: rk808: Convert rk805 buck1/2 to use linear range
It looks like linear range is suitable to describe the voltage table for rk805 buck1/2: selector 0 ~ 59: 0.7125V with uV_step = 12500 selector 60 ~ 62: 1.8V with uV_step = 200000 selector 63: 2.3V With this change, then rk805 buck1/2 can reuse rk808_reg_ops_ranges.
