video: tegra: dc: swap rotated h/v filter check

When determining if the filter should be disabled because input == output,
use the SCAN_COLUMN flag to select the correct dimension.

video: tegra: dc: fix filtering during rotation

SCAN_COLUMN works on the input, filters work on the output. Only input
settings need to be swapped when in SCAN_COLUMN mode (270/90 rotation).

This removes an inadvertant swap of H and V for the filter capabilities.

video: tegra: dc: fix nvsd smooth_k handling

When smooth_k is enabled, the NVSD driver determines
that hardware pixel gain and brightness calculations
are complete when it sees to consecutive and equal
brightness values. However, since multiple raw K
values are mapped to a single brightness value,
this check can be misleading.

To fix this, we continue checking for new brightness
values for a few additional frames after seeing repeating
brightness results. The number of frames is calculated
from smooth_k_incr.

tegra: macallan: panel: enable smooth_k; disable phase_in_adj
input: gpio_keys: Fix disordered wakeup key reports

- If power key is released before gpio_keys_gpio_report_wake() called,
power key press-release events pair will be reported twice and supress
display from coming back up.
- If power key is released before enabling device driver to receive
interrupts, power key release interrupt will be lost due to the previous
pending key press intterupt, and we can only get the released key state.
Change to call gpio_keys_gpio_report_wake() and gpio_keys_report_state()
in gpio_keys_resume_noirq() callback to avoid the disordered reports.
