regulator: tps65917/palmas: Add bypass "On" value
When commit b554e1450658 ("regulator: tps65917/palmas: Add bypass ops for LDOs with bypass capability") introduced bypass capability to palmas regulator, it went with the assumption that regulator regmap helpers just check val against the bypass_mask. Unfortunately, this ignored the explicit "on" and "off" values when the register value is masked with bypass_mask in commit ca5d1b3524b4 ("regulator: helpers: Modify helpers enabling multi-bit control"). With the recent commit dd1a571daee7 ("regulator: helpers: Ensure bypass register field matches ON value"), this issue gets highlighted and fails tps65917/palmas based platforms which need regulators/ldos that have bypass capability. Introduce the bypass_on value appropriately for tps65917/palmas regulator.
