[media] v4l: ti-vpe: register video device only when firmware is loaded

vpe fops(vpe_open in particular) should be called only when VPDMA firmware
is loaded. File operations on the video device are possible the moment it is
registered.

Currently, we register the video device for VPE at driver probe, after calling
a vpdma helper to initialize VPDMA and load firmware. This function is
non-blocking(it calls request_firmware_nowait()), and doesn't ensure that the
firmware is actually loaded when it returns.

We remove the device registration from vpe probe, and move it to a callback
provided by the vpe driver to the vpdma library, through vpdma_create().

The ready field in vpdma_data is no longer needed since we always have firmware
loaded before the device is registered.

A minor problem with this approach is that if the video_register_device
fails(which doesn't really happen), the vpe platform device would be registered.
however, there won't be any v4l2 device corresponding to it.

[media] saa7134: convert to vb2

Convert the saa7134 driver to vb2.

Note that while this uses the vb2-dma-sg version, the VB2_USERPTR mode is
disabled. The DMA hardware only supports DMAing full pages, and in the
USERPTR memory model the first and last scatter-gather buffer is almost
never a full page.

In practice this means that we can't use the VB2_USERPTR mode.

This has been tested with raw video, compressed video, VBI, radio, DVB and
video overlays.

Unfortunately, a vb2 conversion is one of those things you cannot split

     32-bit version would take precedence and we tried to change it to
     the other way around and it didn't work.  From Lv Zheng.

   - A TPM commit related to ACPI _DSM in 3.14 caused the driver to
     refuse to load if a specific _DSM was missing and that broke resume

     the old behavior to load the driver if the _DSM in question is not
     present, but prevent it from using the feature the _DSM is for.

   - ACPI AC driver conversion in 3.13 broke thermal management on at
     least one machine and has to be reverted.  From Guenter Roeck.

   - Two reverts of 3.13 commits that attempted to remove the old ACPI
     battery interface in /proc, but turned out to break some utilities
     still using that interface.  From Lan Tianyu.

   - ACPI processor driver fix to prevent acpi_processor_add() from
     modifying the CPU device's .offline field which leads to breakage
     if the initial online of the CPU fails.  From Igor Mammedov.

   - Two intel_pstate fixes, one to take a BayTrail documentation update
     into account and one to avoid forcing the maximum P-state on init
     which causes CPU PM trouble on systems with P-states coordination

The new renameat2 syscall provides all the functionality of renameat
with an additional flags argument, so make renameat optional so that
future architectures can omit it without getting a warning.
