This implements the ioctl used for mapping GEM objects into memory.
This needs a unit test in glamo-dri-tests, but for the time being appears to
make X.org less segfaulty.

This allows command sequences to make use of buffer objects by providing
their GEM handles.
It also reorganises the code a bit, and adds a lot of missing security stuff.

This removes a lot of debugging. We can't afford to splurge out a
page of printk()s on every command submission.

We must enable the clock divider for the 2D engine in order for

This allows glamo_cmdq_wait() to timeout.
We will probably need to substitute this for something better later on, but for the
time being I wanted to avoid a deadlock if the command queue never cleared.

Tidy up the code in glamodrm_probe by doing glamodrm->gdrm

To disable the workaround at run-time run:
echo 0 > /sys/class/i2c-adapter/i2c-0/0-0073/pcf50633-regltr.9/glamo3362.0/glamo-fb.0/xglamo_hack
I guess I should add a compile option now to completely disable the workaround but let's call
this an enhancement and let's close the bug now.
By default the workaround is enabled.

This reverts commit bd4b7e8e84ab43a13a4620b001d52d373c2122b3 which brought
WSOD back for some devices.
It was reported that the problem does not happen with Qi and it
seem it is good news. See:

Space transition between sleep-in and sleep-out of at least
120 ms as mentionned in the spec. Also, made sure the LCM
is moved into sleep state before the pixel clock is turned off.
To do so, I've modified glamo-fb to send FB_BLANK_POWERDOWN before
turning off the pixel clock. Also fixed various violation of coding
style. This patch should reduce the risk of white screen.

e2c0650efa751a6a2220618695fa41a2a5e7d23c introduced a platform-specific
hack to check if the MMC driver and hardware handle busy signaling from
the device properly.
Since this seems to be the case, we can revert this hack now.
