813e40f4ca exception_asm.S: skip msr hcr_el2 if not required
When guarded exception levels are enabled hcr_el2 can no longer be written to from EL2.
A future commit will however use el1_call to jump to GL1. It will setup hcr_el2 before
enabling GXF such that the write doesn't have to happen in el1_call anymore
