Recently, MEDIA_CEC_SUPPORT became indepedent of MEDIA_SUPPORT.
However, if MEDIA_SUPPORT is not enabled, MEDIA_SUPPORT_FILTER is not
defined, and MEDIA_CEC_SUPPORT is thus enabled by default, which is not
desirable.
Fix this by adding a dependency on MEDIA_CEC_SUPPORT to the default
configuration.

Previously, the output format was programmed as part of the ioctl()
handler. However, this has two problems:
1) If there are multiple active streams with different output
formats, the hardware will use whichever format was set last
for both streams. Similarly, an ioctl() done in an inactive
context will wrongly affect other active contexts.
2) The registers are written while the device is not actively
streaming. To enable runtime PM tied to the streaming state,
all hardware access needs to be moved inside cedrus_device_run().
The call to cedrus_dst_format_set() is now placed just before the
codec-specific callback that programs the hardware.

There's a hack at the driver that selects a different table
for a BYT tablet, which sets the maximum frequency to 320 MHz,
instead of 400 MHz.
After looking at the Intel Aero Yocto's version from:
https://download.01.org/aero/deb/pool/main/l/linux-4.4.76-aero-1.3/
It was noticed that this depends on an Android-specific modprobe parameter,
which uses a macro (INTEL_MID_BOARD) from this file:
arch/x86/include/asm/spid.h
>From the comments there, it looks like this macro parses a
variable passed at boot time:
cmdline : androidboot.spid=vend:cust:manu:plat:prod:hard
The devices in question are identified there as:
INTEL_BYT_TABLET_BLK_PRO = 0x0000
INTEL_BYT_TABLET_BLK_ENG = 0x8000
Well, this is something that we don't have upstream. So,
without further details about that, we can't really parse it.
If we ever end supporting those devices with the upstream driver,
this patch can be reverted and the device can be detected
via DMI (or maybe via PCI ID?).

It was reported that older GCCs compile smm_test in a way that breaks
it completely:

func 7ffffffd idx 830 rax 0 rbx 0 rcx 0 rdx 0, cpuid entry not found
...
kvm_exit: reason EXIT_MSR rip 0x40abd9 info 0 0
kvm_msr: msr_read 487 = 0x0 (#GP)
...
Note, '7ffffffd' was supposed to be '80000001' as we're checking for
SVM. Dropping '-O2' from compiler flags help. Turns out, asm block in
sync_with_host() is wrong. We us 'in 0xe, %%al' instruction to sync
with the host and in 'AL' register we actually pass the parameter
(stage) but after sync 'AL' gets written to but GCC thinks the value
is still there and uses it to compute 'EAX' for 'cpuid'.
smm_test can't fully use standard ucall() framework as we need to
write a very simple SMI handler there. Fix the immediate issue by
making RAX input/output operand. While on it, make sync_with_host()
static inline.
