Revert "ion: Backport from CAF kk_2.7_rb1.33"

Camera drivers are experiencing the kernel BUG in ion_free with these new ION drivers, causing the device to reboot during camera use. Additionally, there is a strange glitch where a red border appears on the screen for a split second.

This reverts commit 0aa493ce39e6d194beec49196a5ec5221519e353.

Revert "vidc: Backport from CAF kk_2.7_rb1.34"

Gah! These drivers require the newer ION drivers I backported, but there are issues with those ION drivers (see the ION driver-upgrade revert).
