In preparation for some patches to optmize the system
heap code, rework the dmabuf exporter to utilize sgtables rather
then pageslists for tracking the associated pages.
This will allow for large order page allocations, as well as
more efficient page pooling.
In doing so, the system heap stops using the heap-helpers logic
which sadly is not quite as generic as I was hoping it to be, so
this patch adds heap specific implementations of the dma_buf_ops
function handlers.

Instead of moving meson_dw_hdmi_init() around which breaks existing
platform, let's enable the clock meson_dw_hdmi_init() depends on.
This means we don't have to worry about this clock being enabled or
not, depending on the boot-loader features.
Fixes: b33340e33acd ("drm/meson: dw-hdmi: Ensure that clocks are enabled before touching the TOP registers")

The HDMI driver request clocks early, but never disable them, leaving
the clocks on even when the driver is removed.
Fix it by slightly refactoring the clock code, and register a devm
action that will eventually disable/unprepare the enabled clocks.

The init sequence consist of a number of unknown settings
for the display controller. This patch achieves two things:
- Fix an error that must have happened when the driver was
converted from the backlight subsystem: the 0xb8
configuration command was lost and added as a tail to
the previous command.
- Update some minor settings in some bytes here and there
according to changes in the Samsung GT-I9070 and
Samsung GT-S7710 code dumps. Since two other devices use
these settings they probably reflect trimmings later
found to be better for the display rather than
customizations for these devices.

It's probably full of bugs ready for exploiting by userspace. And
there's not going to be any userspace for this without any of the drm
legacy drivers enabled too. So just couple it together.
Note that the frontend is only the /dev/agp ioctl interface, which per
Adam is only used by the i810 userspace drivers. All other drivers go
through the drm bufmap agp handling abstraction apparently.
v2: Augment commit message a bit from m-l feedback.
