regulator: tps65917/palmas: Add bypass "On" value

Browse Source 
When commit b554e14506 ("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 ca5d1b3524
("regulator: helpers: Modify helpers enabling multi-bit control").

With the recent commit dd1a571dae ("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.
