* [dm][regulator] update regulator
Replace the regulator framework spinlock with a mutex
because regulator operations may sleep.
Move always-on policy into the regulator core,
keep an initial enable reference for always-on supplies,
prevent the last disable from turning them off,
and let fixed/GPIO providers report and control their actual hardware state.

- add msh commands to inspect/operate power supplies and regulators
- expose snapshot/name helpers so shells and daemons can enumerate nodes safely
- add current support for regulator
- relax DM-only constraints in power/regulator stacks so basic builds work without DM/OFW
- solve the problem of enabling counting for regulator
1. Add the regulator driver framework.
2. Add the generic voltage and current regulator API support
for drivers.
