media: dvb: Optimize setting of secure-mode

Secure mode should be set on feed basis therefore TS and section
feeds should expose API to to set their secure mode. The secure-mode
is saved as part of the feed structure which already exists
instead of allocating special memory to save this info.

media: dvb: Fix invocation of secure-demux when playing from TSIF

secure-demux processing function expects to receive a fixed
start address aligned to 4KB along with a read pointer, the
code provided the current address along with a read pointer
set to 0 as fixed value. This may cause the start address not
to be aligned to 4KB.

Add support for kernel space client:
    - add support for starting secure app by kernel client
    - add support for shutting down secure app by kernel client
    - add support for sending command to secure app loaded by
      kernel space client(s)

The above is needed for allowing kernel modules to communicate
with app running in secure domain.

USB: ks_bridge: Fix PM usage counter mismatch

The runtime PM is disabled for a device during suspend.  It is
enabled again just before resuming  the device.  The resume method
of USB interface drivers are called while resuming a USB device.  As
USB device is the parent of an interface, the interface resume is
blocked till USB device resume is completed.  If interface driver
call any runtime PM API before interface runtime PM is enabled, it
fails with -EACCESS error.

The USB runtime wrapper usb_autopm_get_interface() decrements PM usage
counter when get_sync() is failed.  The current code is decrementing
the PM usage counter even when an error code is returned from
usb_autopm_get_interface().  Due to this double decrementing, the KS
bridge interface PM usage counter is becoming negative after several
suspend and resume cycles.  Once the PM usage counter becomes negative,
the interface runtime PM state will never become active.  That means,
USB device suspend can happen even when a Tx URB is pending from ks
bridge driver.

The fix is trivial.  Don't decrement PM usage counter when error code
is returned from usb_autopm_get_interface().

USB: ci13xxx_udc: Don't flush inactive endpoints

The endpoint must be flushed prior to retiring pending requests.
This is done during disabling an endpoint.  Don't flush an endpoint
if there are no pending requests.  According databook flushing
endpoint may take large amount of time.  This optimization will
make USB disconnect/reset processing a little bit faster.

USB: ci13xxx_udc: Skip flushing endpoints upon failure

Flushing an endpoint involve polling ENDPTFLUSH and ENDPTSTAT
registers.  The worst case timeout is 100 msec for each endpoint.
The reason for failure is unknown.  When flushing an endpoint
fails, successive flushing of remaining endpoints are also failing.
Hence skip flushing remaining endpoints.  Reset this condition
upon USB bus reset.
