tests/tcg/hexagon: fix check_rev_gating with newer toolchain
The check_rev_gating test is compiled with -mv66, but the final linkage step does not specify the CPU version. The v22.1.0 toolchain contains a crt1.o compiled for v68, so the linker resolves the v66 + v68 linkage by selecting the highest version. The resulting binary then executes v68 instructions without gating, leading to a segfault. Fix this by passing -cpu v66 to QEMU when running the test, so that the emulated CPU matches the intended v66 target and the revision gating mechanism works as expected.
