[Intel-gfx] [PATCH] drm/i915: Don't enable WaIncreaseLatencyIPCEnabled when IPC is disabled

[Intel-gfx] [PATCH] drm/i915: Don't enable WaIncreaseLatencyIPCEnabled when IPC is disabled

[Sultan Alsawaf]

From: Sultan Alsawaf <sultan@kerneltoast.com>

In commit 5a7d202b1574, a logical AND was erroneously changed to an OR,
causing WaIncreaseLatencyIPCEnabled to be enabled unconditionally for
kabylake and coffeelake, even when IPC is disabled. Fix the logic so
that WaIncreaseLatencyIPCEnabled is only used when IPC is enabled.
