regulator: max8997: Use uV in voltage_map_desc
Current code does integer division (min_vol = min_uV / 1000) before pass
min_vol to max8997_get_voltage_proper_val().
So it is possible min_vol is truncated to a smaller value.
For example, if the request min_uV is 800900 for ldo.
min_vol = 800900 / 1000 = 800 (mV)
Then max8997_get_voltage_proper_val returns 800 mV for this case which is lower
than the requested voltage.
Use uV rather than mV in voltage_map_desc to prevent truncation by integer
division.
