There is a possibility of PMI detecting SDP as a floating charger
when connected to a PC. Workaround this issue by starting
peripheral stack for floating charger as well. After 10 sec check
for USB device enumeration using gadget USB state. If device is
indeed connected to SDP gadget usb state will be
USB_STATE_DEFAULT or higher.

The charger driver's implementation of power_supply_set_property() for
POWER_SUPPLY_CURRENT_MAX currently uses a mutex. Since
sleeping is disallowed in this case, instead schedule a
work function to do the call.

Instead of having the controller driver call the PHY's DP/DM
properties on behalf of the charger driver to enable and disable
the regulator, allow the PHY to expose a regulator device.
The charger driver then obtains a handle to this regulator to
perform regulator enable and disable directly.

This patch removes the deprecated notifier API of extcon framwork
and then use the new extcon API with the unique id to indicate
the each external connector (USB, USB-HOST).
Alter deprecated API as following:
- extcon_register_interest() -> extcon_register_notifier()
- extcon_get_cable_state(*edev, char *) -> extcon_get_cable_state_(*edev, id)

Implement good battery algorithm defined in the battery charging V1.2 spec
for detecting different charging ports. USB hardware is put into low power
mode when connected to a dedicated charging port. vbus_draw and set_power
methods are implemented for determining the allowed current from Host in
different states (un-configured/suspend/configured).
The charger block is implemented using vendor specific registers and the
PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60
and MSM7x30(45nm PHY). The PHY vendor and product id registers are not
implemented in the above chipsets. Hence PHY type is passed via platform
data.
