[PATCH v2] drm/display: Drop obsolete dependency on COMPILE_TEST

[Jean Delvare]

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), it
is possible to test-build any driver which depends on OF on any
architecture by explicitly selecting OF. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

To avoid reintroducing the randconfig bug originally fixed by commit
876271118aa4 ("drm/display: Fix build error without CONFIG_OF"),
DRM_MSM which selects DRM_DISPLAY_DP_HELPER must explicitly depend
on OF. This is consistent with what all other DRM drivers are doing.

For regular builds, this is a no-op, as OF is always enabled on
ARCH_QCOM and SOC_IMX5. So this change only affects test builds. As
explained before, allowing test builds only when OF is enabled
improves the quality of these test builds, as the result is then
closer to how the code is built on its intended targets.

Changes since v1:
* Let DRM_MSM depend on OF so that random test builds won't break.
