regulator: tps65086: Fix 25mV ranges for BUCK regulators
The BUCK regulators 3, 4, and 5 also have a 10mV step mode, adjust the tables and logic to reflect the data-sheet for these regulators. fixes: d2a2e729a666 ("regulator: tps65086: Add regulator driver for the TPS65086 PMIC") Signed-off-by: Andrew F.
