Subject: [PATCH] ARM: imx: Drop imx_anatop_init()

From: Andrey Smirnov <[email-masked]>
Date: Wed, 31 Jul 2019 11:01:31 -0700

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_init() 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.
