msm_serial_hs: Fix synchronization between ADM and UART Cores

With current UART Core programming sequence, it is seen that ADM
and UART Core are going out of sync in few usecases with regression.
It is fixed by using Force RxStale feature of UART Core from
set_termios() and sending discard flush to ADM which would terminate
currently queued UART RX CMD to ADM. Add termios_in_progress check
to make decision about what kind flush to send on receiving RxStale
interrupt. It makes set_termios() more reboust and also keeps ADM
and UART Core in-sync.

Add dma_in_flight to keep check of UART Rx CMD status and BUG_ON if
UART driver is trying to queue one more UART RX CMD to ADM as UART
driver re-uses same UART RX CMD.

This change also adds check of currently set uartclk rate and next
required uartclk rate for new baud rate. If both are same it would
not call clk_set_rate() to set same uartclk rate again.

UART baud rate change request (i.e. executing set_termios()) can come
asynchronously and time to program ADM hardware with queued CMD by ADM
driver is non-deterministic. It is required by UART driver to confirm
that queued RX CMD is programmed with ADM hardware before going with
requested baud rate change operation. Hence this change wait in
set_termios() for ADM driver to program queued RX CMD before going ahead
with baud rate. Otherwise ADM may encounter data bus error with UART RX
channel which is unrecoverable.

msm: vidc: Separate meta buffers support in secure mode
msm: vidc: Remove kernel mapping on input/output buffers

This change will remove the kernel mapping of input and
output buffers for both video encoder and decoder to
avoid the errors resulting from ion_map_kernel() for
high resolution video concurrency use cases due to the
limited vmalloc space. It also removed the metadata
processing in kerner video driver as kernel virtual
address is removed. The metadata processing can be
done in user space video component.

msm: vidc: Fix metadata buffer size issue

- Metadata buffer size is being set to zero when
  client calls set buffer requirements to video driver.
  This change fix it by properly assigning the
  metadata buffer size to video driver.
- When continuous mode enabled, do not get min_dpb
  from resource tracker for non-H264 codecs,
  for H264 codec get min_dpb from resource tracker.

msm: vidc: Free buffer pool entry and then delete address table

Free the buffer pool entry first and then delete the
address table (which will unmap the buffer with iommu)
else we might get a corner case where the entry was not
freed but the buffer is unmapped and the next buffer is
mapped with the same physical address which is still
available in the buffer pool entry, which results in
video recording failure.

msm: Add support for ION Flushing without virtual address

Video has very large buffers to be flushed. Due to lack of
vmalloc space, ion_map_kernel cannot be called on each of
the video buffers. With this change the ion handle can be
flushed without the need of the kernel mapping.
