Refine locking inside of syscon driver.
In some cases, the syscon driver may be used by consumer requiring better
control about locking (ie. it may be used as registe file provider for clock
driver which needs locked access to multiple registers).
Add fine locking protocol methods together with bunch of helper functions
in syscon driver and implement this functionality in syscon_generic driver.

regulator: Add a regnode_set_constraint function
This method check that boot_on or always_on is set to 1 and if it
is it will try to enable the regulator.
The binding docs aren't clear on what to do
regulator: Add a regnode_set_constraint function
This method check that boot_on or always_on is set to 1 and if it
is it will try to enable the regulator.
The binding docs aren't clear on what to do but Linux enable the regulator
if any of those properties is set so we want to do the same.
The function first check the status to see if the regulator is
already enabled it then get the voltage to check if it is in a acceptable
range and then enables it.
This will be either called from the regnode_init method (if it's needed by the platform)
or by a SYSINIT at SI_SUB_LAST
