If a partner port sends a packet at approximately the same time as we
send a packet, we may end up with the initial packet followed by the
GOOD_CRC reply in our HW FIFO. Don't automatically discard the first
packet in the FIFO. Instead, discard the packet only if it's a GOOD_CRC
packet. And, modify our get_message function to automatically discard
GOOD_CRC in search of a meaningful packet.
In addition, due to interrupt latency, we can't rely on receiving one
interrupt per incoming packet. If our Rx FIFO is non-empty, assume that
it contains at least one packet.

With the atomic API, it is possible that a single commit affects
multiple crtcs. If the user requests an event with that commit, one
event will be sent for each CRTC, but it is not possible to distinguish
which crtc an event is for in user space. To solve this, the reserved
field in struct drm_vblank_event is repurposed to include the crtc_id
which the event is for.
The DRM_CAP_CRTC_IN_VBLANK_EVENT is added to allow userspace to query if
the crtc field will be set properly.

The PD spec define the source should ensure that a message requesting
a response is responded within 30ms(tSenderResponse). But if the
message responded is received close to 30ms, we may hit the case:
tcpm_get_message(); //get the data and close to 30ms
... takes about 600us, meanwhile the 30ms timer came.
auto_vdm_machine
vdm_send... //we get the message, but timeout.
So, let's ignored the timeout if we get the message.

Introduce support for rockchip gamma table,
Rockchip have two version gamma table design:
The old version design was introduced by Dominik Behr's gamma patch
(https://chromium-review.googlesource.com/272209):
Gamma table has to be uploaded when the LUT is disabled which only takes
effect at the end of a frame, therefore actual hardware updates is done
from a worker and can take more than one frame.
In order to solve gamma table switch issues, after rk3399,
H/W add a gamma table update mechanism, can update without lut disable.
And gamma table's size also has two version:
one is 10 bit per component, 1024 entries,
the other one is 8 bit per component, 256 entries

lock the mutex of vop when scaling frequency, so vop_crtc will not be
disabled when it is waiting for line flag.

It may disable vop_crtc when waiting for line flag, in this case,
we would not get line flag any more. So the lock should be added
to prevent rockchip_wait_line_flag() from vop_crtc_disable();
