Subject: [PATCH v1] perf: starfive: fix 64-bit only COMPILE_TEST condition

From: Conor Dooley <conor.dooley@...rochip.com>

ARCH_STARFIVE is not restricted to 64-bit platforms, so while Will's
addition of a 64-bit only condition satisfied the build robots doing
COMPILE_TEST builds, Palmer ran into the same problems with writeq()
being undefined during regular rv32 builds.

Promote the dependency on 64-bit to its own `depends on` so that the
driver can never be included in 32-bit builds.

Reported-by: Palmer Dabbelt <palmer@...osinc.com>
Fixes: c2b24812f7bc ("perf: starfive: Add StarLink PMU support")
Fixes: f0dbc6d0de38 ("perf: starfive: Only allow COMPILE_TEST for 64-bit architectures")
