Subject: [PATCH v5 18/20] extcon: intel-cht-wc: Refactor cht_wc_extcon_get_charger()
This is a preparation patch for adding support for registering
a power_supply class device.
Setting usbsrc to "CHT_WC_USBSRC_TYPE_SDP << CHT_WC_USBSRC_TYPE_SHIFT"
will make the following switch-case return EXTCON_CHG_USB_SDP
just as before, so there is no functional change.
