drm/tegra: Properly align stride for framebuffers
Tegra20 and Tegra30 both required the buffer line stride to be aligned
on 8 byte boundaries. Tegra114 and Tegra124 increased the alignment to
64 bytes. Introduce a parameter to specify the alignment requirements
for each display controller and round up the pitch of newly allocated
framebuffers appropriately.

drm/tegra: Implement more tiling modes
Tegra124 supports a block-linear mode in addition to the regular pitch
linear and tiled modes. Add support for these by moving the internal
representation into a structure rather than a simple flag.

drm/tegra: Implement race-free hotplug detection
A race condition currently exists on Tegra, where it can happen that a
monitor attached via HDMI isn't detected during the initial FB helper
setup, but the hotplug event happens too early to be processed by the
poll helpers because they haven't been initialized yet. This happens
because on some boards the HDMI driver can control the regulator that
supplies the +5V pin on the HDMI connector. Therefore depending on the
timing between the initialization of the HDMI driver and the rest of
DRM, it's possible that the monitor returns the hotplug signal right
within the window where we would miss it.
Unfortunately, drm_kms_helper_poll_init() will wreak havoc when called
before at least some parts of the FB helpers have been set up.
This commit fixes this by splitting out the minimum of initialization
required to make drm_kms_helper_poll_init() work into a separate
function that can be called early. It is then safe to move all of the
poll helper initialization to an earlier point in time (before the
HDMI output driver has a chance to enable the +5V supply). That way if
the hotplug signal is returned before the initial FB helper setup, the
monitor will be forcefully detected at that point, and if the hotplug
signal is returned after that it will be properly handled by the poll
helpers.

drm/tegra: dc - Add YUYV support
YUYV is UYVY with swapped bytes. Luckily the Tegra DC hardware can swap
bytes during scan-out, so supporting YUYV is simply a matter of writing
the correct value to the byteswap register.
This patch modifies tegra_dc_format() to return the byte swap parameter
via an output parameter in addition to returning the pixel format. Many
other formats can potentially be supported in a similar way.

drm/tegra: Allocate resources at probe time
Since the .init() and .exit() functions are executed whenever the DRM
driver is loaded or unloaded, care must be taken not to use them for
resource allocation. Otherwise deferred probing cannot be used, since
the .init() and .exit() are not run at probe time. Similarly the code
that frees resources must be run at .remove() time. If it is run from
the .exit() function, it can release resources multiple times.
To handle this more consistently, rename the tegra_output_parse_dt()
function to tegra_output_probe() and introduce tegra_output_remove()
which can be used to free output-related resources.
