Currently there are no documentation for EXTCON_CHG_USB_SLOW/FAST charger connector. These names don't mean much and no guide to tell users how to use it, thus try to add documentation to make them clear.

- the USB connector, which means EXTCON_CHG_USB_SDP should always
- appear together with EXTCON_USB. The same as ACA charger connector,
- EXTCON_CHG_USB_ACA would normally appear with EXTCON_USB_HOST.
- A cable of type EXTCON_CHG_USB_SLOW can provide at least 500mA of
- current at 5V. A cable of type EXTCON_CHG_USB_FAST can provide at
- least 1A of current at 5V.
When I applied this patch, I use the 'connector expression' instead of 'cable'.

Applied it. Thanks.
