ANDROID: i915: Provide workaround to build i915 as vendor module

GKI does not allow to build any vendor module which uses
symbol_get/symbol_put as symbol lookup circumvents all ABI checking.

Stub out problematic code if CONFIG_INTEL_IPS is not used and
scream during compilation otherwise.

Bug: 352497771
Bug: 375084559
TEST=two test cases:
1. Enable CONFIG_INTEL_IPS, build AL device, check if compilation fail
2. Disable CONFIG_INTEL_IPS, build AL device, check if compilation passes
   and if KMI symbols do not contain symbol_get/symbol_put.
