Flash LED is a high energy aggregator from system as it is capable
to provide current up to 3750mA for illumination. Therefore, it

is low. Therefore, add a function which can be used by clients like
camera to query the flash current limit before using flash LED. This
protects the system from a possible UVLO condition.

Change to using upstream spmi bus architecture. All the spmi devices,
marked by spmi-dev-container, become platform devices.
spmi-slave-container devices become spmi_devices each representing
a slave. The read/write functions use regmap api's instead of calls to
spmi_ext_register_read/write() implemented by the spmi bus. This
regmap is instantiated per slave.
The spmi bus helper functions like spmi_get_irq get changed to their
platform bus equivalents.
Change Kconfig files include
* Remove dependence on OF_SPMI, MSM_QPNP_INT
* There were few places where an earlier commit
dcc2aedc80746acee589e4b47d3e6adf5d3ec253
missed adding dependence on SPMI along with MSM_SPMI.

* Add depends on ARCH_MSM. ARCH_MSM is used for internal builds.
