[PATCH] phy: qcom-usb-hs: Add depends on EXTCON

[Kishon Vijay Abraham I]

commit e2427b09ba929c2b9 (phy: Add support for Qualcomm's USB HS phy")
while using extcon API's in qcom-usb-hs failed to add
'depends on EXTCON' resulting in the following compile errors if
EXTCON is not enabled.
drivers/built-in.o: In function `qcom_usb_hs_phy_power_off':
phy-qcom-usb-hs.c:(.text+0x1089): undefined reference to 
`extcon_unregister_notifier'
drivers/built-in.o: In function `qcom_usb_hs_phy_probe':
phy-qcom-usb-hs.c:(.text+0x11b5): undefined reference to 
`extcon_get_edev_by_phandle'
drivers/built-in.o: In function `qcom_usb_hs_phy_power_on':
phy-qcom-usb-hs.c:(.text+0x128e): undefined reference to `extcon_get_state'
phy-qcom-usb-hs.c:(.text+0x12a9): undefined reference to 
`extcon_register_notifier'

Fix it here.
