Update extcon for 3.13

This patchset modify extcon core to remove unnecessary allocation sequence for
'dev' instance and change extcon_dev_register() interface. extcon-gpio use
gpiolib API to get debounce time and include small fix of extcon core/device
driver.

Detailed description for patchset:
1. Modify extcon core driver
- The extcon-gpio driver use gpio_set_debounce() API provided from gpiolib
if gpio driver for SoC support gpio_set_debounce() function and support 'gpio_
activ_low' filed to check whether gpio active state is 1(high) or 0(low).
- Change field type of 'dev' in structure extcon_dev and remove the sequence
of allocating memory of 'struct dev' on extcon_dev_register() function because
extcon device must need 'struct device.
- Change extcon_dev_register() prototype to simplify it and remove unnecessary
parameter as below:

2. Fix coding style and typo
- extcon core     : Fix indentation coding style and remove unnecessary casting
- extcon-max8997  : Fix checkpatch warning
- extcon-max77693 : Fix checkpatch warning
- extcon-arizona  : Fix typo of comment and modify minor issue
- extcon-palmas   : Use dev_get_platdata()

3. Modify extcon-arizona driver
- Modify minor issue about micbias and comparision statement
