Vineet Gupta 8b9187e7df ARCv2: don't assume core 0x54 has dual issue
[ Upstream commit 7b2e932f633bcb7b190fc7031ce6dac75f8c3472 ]

The first release of core4 (0x54) was dual issue only (HS4x).
Newer releases allow hardware to be configured as single issue (HS3x)
or dual issue.

Prevent accessing a HS4x only aux register in HS3x, which otherwise
leads to illegal instruction exceptions
