Paul Burton 12dbb04f2a MIPS: genex: Add Loongson3 LL/SC workaround to ejtag_debug_handler
In ejtag_debug_handler we use LL & SC instructions to acquire & release
an open-coded spinlock. For Loongson3 systems affected by LL/SC errata
this requires that we insert a sync instruction prior to the LL in order
to ensure correct behavior of the LL/SC loop.
