Subject: [Patch v2 1/3] perf arch: Update arch headers to use relative UAPI paths

The architectural specific headers perf_regs.h currently rely on the
host architecture's 'asm/perf_regs.h'. This can lead to compilation
inconsistencies or failures when including and building perf for a
target architecture that differs from the host's architecture.

Explicitly point to the UAPI headers within the tools source tree using
relative paths. This ensures that perf is always built against the
intended architecture.

No functional changes are intended.
