ARM: imx: Drop imx_anatop_usb_chrg_detect_disable()
With commit b5bbe2235361 ("usb: phy: mxs: Disable external charger
detect in mxs_phy_hw_init()") in tree all of the necessary charger
setup is done by the USB PHY driver which covers all of the affected
i.MX6 SoCs.
NOTE: imx_anatop_usb_chrg_detect_disable() was also called for i.MX7D,
but looking at its datasheet it appears to have a different USB PHY IP
block, so executing i.MX6 charger disable configuration seems
unnecessary.
