regulator: tps65912: Convert tps65912_ops_ldo to use linear ranges
The ldo voltage table is composed of linear ranges.
Below is the equation in original code (tps65912_vsel_to_uv_ldo):
0 ... 32: uv = vsel * 25000 + 800000;
33 ... 60: uv = (vsel - 32) * 50000 + 1600000;
= (vsel -33) * 50000 + 1650000;
61 ...63: uv = (vsel - 60) * 100000 + 3000000;
= (vsel - 61) * 100000 + 3100000;
This patch converts tps65912_ops_ldo to use multiple linear ranges APIs.
