This is a re-write of the Motorola mdm6600_modem driver.
The usb_serial_generic_* handlers actually cover the USB bulk to serial data
path. So that code disappears.
The USB interrupt data to TIOCMGET ioctl path does not appear to be used by
pppd in userspace, using a temporary BUG_ON() to confirm.
So we end up with very little but a hook to register generic usb-serial
handlers for the MDM6600 vendor id.
I have not spent time testing behavior in low-power-modes, it is likely I will
need to over-ride some of the generic handlers at that point.

Instead just allow userspace to turn on and off the backlight when
entering suspend. Otherwise we get a race condition on some hardware
where the backlight does not go off.

Disable cpcap interrupts at suspend and re-enable at resume, to avoid
processing interrupts while the SPI controller is suspended.

This allow's Motorola's mdm6600_modem driver to work with suspend.
Patch provided by Motorola.
mdm6600_modem will shortly be replaced by a re-write, but its useful to commit
this update for easier A/B testing.

Configure GPIO_PZ5 to control the charge LED. For now, charge LEDs
are enabled when device is powered up. GPIO is also exported to
enable factory testing.

If Stingray is powered up with a charger already attached, the battery
driver would not report charging to the system, even though the battery
was being charged. This charges the DS2781 battery driver to check
if a charger is already present when the driver is probed.

Stingray will initially ship with the DS2780 instead of the DS2781
gas gauge. The same DS2781 driver will work, but need to look for
the DS2780 family code.

The current being reported by the DS2781 battery driver was off
due to the incorrect value being used for Rsnsp. The DS2781 has
a register with the correct value, so use it instead of a hard
coded value.
