Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that
MI_FLUSH would flush the TLBs in addition to the rest of the caches
indicated in the MI_FLUSH command.  However starting with Ivybridge, the
register defaults to 0x2800 out of reset, meaning that to invalidate the
TLB we need to use PIPE_CONTROL.  Since we're not doing that yet, go
back to the old default so things work.

Currently, error handling code in this function calls the function
sata_dwc_port_stop, but this function has essentially no effect if hsdevp
has not been stored in ap, which is the case throughout this function.  The
only effect is to print a debugging message including ap->print_id.

The code is rewritten to not call sata_dwc_port_stop, but instead to jump
to a local label that prints the original error message and the print_id
information.  In the case where hsdevp has been already allocated (but not
yet stored in ap), this value is freed as well.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

  - use dev_get_drvdata
v3:
  - add missing clk_put() calls
  - use platform_get_irq()
  - fix resume code to avoid disabling IORDY on resume
v4:
  - Remove EXPERIMENTAL and switch to depends on ARCH_MXC
  - Use devm_kzalloc()
  - make clock a must-have

Kirill Shutemov found problems with the non-upstream IMG driver where the
use of extra DRM encoder/connector types caused random crashes when the DRM
layer tried to display their matching name. This removes the MIPI types
matching the changes Pauli Nieminen made to the non upstream driver set.

As Pauli points out:
" MIPI (or DSI) is protocol specification on top of LVDS serial bus. That
 makes it resonable to call MIPI connectors and encoders LVDS."

(and indeed they may also be HDMI convertors or similar when we want to
 report a more useful to end user result)

Attempting to try and turn off disconnected display hw in the
hotput handler lead to more problems than it helped.  For
now just register an event and only attempt the do something
interesting with DP.  Other connectors are just too problematic:
- Some systems have an HPD pin assigned to LVDS, but it's rarely
if ever connected properly and we don't really care about hpd
events on LVDS anyway since it's always connected.
- The HPD pin is wired up correctly for eDP, but we don't really
have to do anything since the events since it's always connected.
- Some HPD pins fire more than once when you connect/disconnect
- etc.
