[PATCH 1/3] KVM: arm64: fix include path for ring buffer implementation

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

The simple_ring_buffer.c file is in the source tree rather than
generated at build time, so the include path is wrong when using
separate object trees:

arch/arm64/kvm/hyp/nvhe/trace.c:16:10: fatal error: simple_ring_buffer.c: No such file or directory
   16 | #include "simple_ring_buffer.c"

Include it from the source tree instead.

Fixes: 680a04c333fa ("KVM: arm64: Add tracing capability for the nVHE/pKVM hyp")
