300bac7fb8 power_supply: Convert drivers/power/* to use module_platform_driver()
This patch converts the drivers in drivers/power/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

2785cefc98 isp1704_charger: Allow board specific powering routine
The ISP1704/1707 chip can be put to full power down
state by asserting the CHIP_SEL line. This patch enables
platform or board specific hooks to put the device into
power down mode in case not needed.

This patch is a preparation for enabling this powering
routine in n900 (rx-51) devices.

Thanks to Heikki Krogerus for helping out with the patch.

e1a85694e0 isp1704_charger: Detect charger after probe
If the device is booted up with cable connected, or the
module is loaded after plugging in the cable, the
notification has come and gone, so not relying on it at
probe time. Instead this checks the VBUS level manually
after probe.

isp1704_test_ulpi() is the first place that needs isp->dev
member, so it must be set before calling the function.

bac43b2050 isp1704_charger: Detect HUB/Host chargers
To avoid breaking high speed chirp handshaking with CDP
chargers, no more then 500mA should be drawn. To make sure
of this, utilizing current_max property. After the device
has enumerated, it's safe to draw the maximum 1800mA as
defined in the Battery Charging Specification. This can be
also used with normal USB connection if the controller sends
ENUMERATED notification with the milliamps as data.

From now on the online property indicates VBUS, present
property if there is a charger and current_max the milliamps
possible to draw from VBUS.
