Adjust girq_regs to avoid flexible-array-like behaviors

[Snape3058]

Struct girq_regs has an array field of length 1 at its end. Since this field is never used in the code base, we can replace it with a non-array field of its original element type to remove the flexible-array-like behaviors and avoid using a flexible array file in the middle of a struct or defining an array of flexible array struct type.

Fixes #84251
