drm/i915: Fix spelling mistake in i915_reg.h

Fix typo: "TRIGER" --> "TRIGGER"

The two misplelled macros:

1) OAREPORTTRIG1_EDGE_LEVEL_TRIGER_SELECT_MASK
2) OAREPORTTRIG5_EDGE_LEVEL_TRIGER_SELECT_MASK

are not used in any other sources of the kernel,
so this change can be consider only a local change
for the i915_reg.h file.
