drm/i915: Add relocation exceptions for two other platforms
For topic/intel-for-CI branch only.
We have established previously we stop using relocations starting
from gen12 platforms with Tigerlake as an exception. We keep this
statement but we want to enable relocations conditionally for
Alderlake S+P under require_force_probe flag set.
Keeping relocations under require_force_probe flag is interim solution
until IGTs will be rewritten to use softpin.
v2: - remove inline from function definition (Jani)
- fix indentation
v3: change to GRAPHICS_VER() (Zbigniew)
v4: remove RKL from flag as it is already shipped (Rodrigo)
v5: prepare patch to be used within topic/intel-for-CI branch only
v6: change comment (Rodrigo)
