Peter Chen d268e9bc23 usb: chipidea: retire flag CI_HDRC_PULLUP_ON_VBUS
Currently, the controller only runs when the ci->vbus_active is true.
So the flag CI_HDRC_PULLUP_ON_VBUS is useless no longer.
If the user doesn't have otgsc, he/she needs to change ci_handle_vbus_change
to update ci->vbus_active.

Lothar Waßmann 769d92c411 usb: chipidea: ci_hdrc_imx: remove an unsolicited module_put() call from ci_hdrc_imx_remove()
This prevents the USB PHY refcount to be decremented below zero upon
unloading the ci-hdrc-imx module.

Fabio Estevam 046916de11 usb: chipidea: ci_hdrc_imx: access phy via private data
commit ea1418b5f1 (usb: chipidea: i.MX: use devm_usb_get_phy_by_phandle to get
phy) causes the USB host to miss the disconnect/connect events.

In order to reproduce this problem:

- Insert a USB thumb into the USB host port (connection is detected)
- Remove it (no disconnect event will be reported)
- Insert the USB thumb again (connection is not detected)

Fix this problem by accessing the usb_phy structure using the private data
instead of accessing a local structure.

Tested on a mx28evk board.

Alexander Shishkin 8e22978c57 usb: chipidea: drop "13xxx" infix
"ci13xxx" is bad for at least the following reasons:
  * people often mistype it
  * it doesn't add any informational value to the names it's used in
  * it needlessly attracts mail filters

This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending
on the situation. Modules with ci13xxx prefix are also renamed accordingly
and aliases are added for compatibility. Otherwise, no functional changes.
