ENGR00290463 revert exact pages allocator to fix system reboot issue

System reboot occur during 1080p recording if exit MovieStudio after play a mixed clip with single HDMI,

Vivante's intial feedback is alloc_pages_exact/free_pages_exact APIs are not stable in some kernel,
In other side, need check if some memory size miscalculated is hided by this optimization.

Temporarily this optimization shall be reverted to fix the critical issue.

ENGR00279413 pxp/v4l2: get the right framebuffer start address at run…

… time

Previously the driver gets the framebuffer start address at probe time.
But this address might be changed if the framebuffer drivers re-allocate
the frame buffers due to the application changes the yres_virtual.
As a result, some garbage data can be observed on display.
This patch adjusts the way to detect the start address at run time to
fix this problem.

The root cause is cam->enc_counter is not re-initialized to 0 when calls
STREAMOFF ioctl, and then in DQBUF ioctl wait_event_interruptible_timeout()
sees the condition is true and access cam->done_q queue which has no strict

This patch adds the re-initialization and the sanity check.
Also, add the pointer check for memcpy because the destination may be
NULL on UERSPTR mode.

ENGR00274493 mx6sl: csi/v4l: Fix capture incorrect data with format UYVY

There's an interim buffer which should only be used when PxP CSC is used.
Otherwise the video buffer gets incorrect data by copying the content of
interim buffer. The patch fixes this by moving the memcpy to the right place.
