This switches the ARM Integrator to use the new PL11x DRM
driver. We need CMA enabled to get coherent allocations
at all times. The dumb VGA DAC bridge is needed for
the VGA output on the reference designs, and backlight
is needed when using an external display.

PROVE_LOCKING enables LOCKDEP, which causes big overhead on cache and
bus transactions.

On some ARM big.LITTLE architecutres (Exynos 5433) the overhead is really big.
The overhead can be measures using hackbench which will speed up
by x3 times (11sec -> 3.4sec).
When you check transaction on cache or buses, the results are way higher
than normal for the same hackbench test:
L1d cache invalidations: 26mln vs 4mln
L2u cache invalidations: 42mln vs 12mln
bus cyc/access: 30cyc/access vs. 20cyc/access
context switch is x3 times cheaper

Enable this option only when you have some locking issue to investigate.

Enable the base GCC plugin support symbol CONFIG_GCC_PLUGINS for
multi_v7_defconfig so that builds hosted on systems that have a
supported version of GCC along with the prerequisite headers will
allow GCC plugins to be used during the build. At the moment, this
will also enable the ARM per-task stack protector plugin, since
all its remaining Kconfig dependencies are fulfilled by default.

At the same time, enable the structleak plugin. This plugin ensures
that local struct type variables are fully initialized, preventing
inadvertent leaks of kernel state if such variables are shared with
userland. This is a reasonable transformation to apply by default,
since it does not adversely affect performance, and does not affect
GCC compiler diagnostics regarding the use of uninitialized local
variables.
