This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
Fixes#1057
For the framebuffer driver of the i.MX53 platform to work even when u-boot
didn't prepared the display previously, there were some IOMUX routes missing.
Fixes#914
Both 'platform_session/capability.h' and 'platform_session/connection.h'
do not contain platform-specific information. By moving them from
'include/platform/imx53/platform_session/' to 'include/platform_session/',
this patch enables other platforms to reuse them.
* Simplify IPU register definitions using templates
* Distinguish between i.MX53 QSB and SMD board in driver
* Support IPU specific overlay mechanism by framebuffer session extension
