This change implements a new feature to read the cmds response
of the panel from sde connector interface. Sde connector opens
debugfs interface for all the connectors those have support for
cmd receive operation.
Sde connector init module creates rx_cmd debugfs file at
/<debugfs-root>/dri/0/DSI-1/ for DSI-1 connector.
Format for DSI command transfer:
echo "command bytes" > /<debugfs-root/dri/0/DSI-1/rx_cmd
byte-0: the length of received buffer
byte-1: data-type
byte-2: last command. always 0x01
byte-3: channel number
byte-4: flags. MIPI_DSI_MSG_*, must be set to 0xa
byte-5: 0x00
byte-6 and byte-7: command payload length
byte-8 to byte-[8+payload length]: command payload
Example:
echo "0x01 0x06 0x01 0x00 0x0a 0x00 0x00 0x01 0x0a" > rx_cmd
The command receive operations are allowed only if controller
(ex. DSI controller) is in active state.
Read the value of panel response:
cat /<debugfs-root>/dri/0/DSI-1/rx_cmd
returns the value of this command.
nothing - failure, xx xx - success.

Vblank refcount can reach out of sync with below case
1. event_thread triggers the vblank_enable
2. commit_thread triggers the modeset
2.a modeset resets the vblank refcount with mode_set
3. event_thread triggers the vblank_disable
Event 2.a resets the vblank refcount and vblank disable
request after 2.a is going to fail. This can be fixed
by avoiding concurrency between mode_set call and vblank
request.

Trusted VM will be assigned MDSS HW access dynamically only on TUI
use case start boundary. So, any HW access during the boot sequence
will result in stage2 faults. But SDE driver initializes few HW
blocks during the boot up sequence. This change fixes them by either
skipping those accesses, if those registers expected to be programmed
by the Primary VM or postponing those accesses until the HW is
assigned.

Assign default drm device for dma buf_attach when
IOMMMU is not present and for stage-2 only buffers.
Avoid setting lazy_unmap for stage-2 only buffers as
it doesn't have any impact without nested translations.
Assign default drm device when no device is found to
support transitions between secure usecases where
the nested context banks might not be attached back
at the prime_fd_to_handle time. These buffers would
be attached with the correct context bank device
during the delayed_import.

Currently DP driver determines if a mode is DSC capable
based on a DTSI entry and the required number of DSC
to support it. This approach does not scale when there
is an overlap in DSC requirement between DSI displays
and external DP display, thus causing one of the display to
report modes that cannot be supported.
This change compares the resources reserved for DP driver
calculated at initialization time and the currently available
ones to determine the correct number of resources that DP driver
can use. It also adds DSC and topology filtering logic and moves
DSC hardware specific from DP driver to SDE driver.

In Dual display concurrencies there are certain cases where
irq_idx and vblank_refcount state mismatch can occur.
To avoid it, during setup of irq_hw_idx, reset the vblank_refcount
and unregister read ptr irq if not yet done by then along with
maintaining global mutex lock for vblank_refcount.
Also, if register IRQ fails, correct vblank_refcount so
that IRQ registration can be tried again.
