regulator: pfuze100: Simplify pfuze100_set_ramp_delay implementation

Simplify the equation to calculate ramp_delay.
Below equations are equivalent:
  ramp_delay = 25000 / (2 * ramp_delay);
  ramp_delay = 50000 / (4 * ramp_delay);
  ramp_delay = 25000 / (2 * ramp_delay);
  ramp_delay = 12500 / ramp_delay;
So we don't need to read BIT6 of rdev->desc->vsel_reg for applying different
equations.

Also use rdev->desc->vsel_reg instead of run-time calculate register address.
