e used to calculate the vsel values
to be programmed in the VREG_VOLTAGE registers.

Voltage(in mV) = 1000mv + 100mv * (vsel - 1)

Ex: if vsel = 0x9, mV = 1000 + 100 * (9 -1) = 1800mV.

This patch removes all existing VSEL tables for twl6030 adjustable
regulators and just uses the formula directly for vsel calculations
after verifing they fall in the allowed range.
