[PATCH 3/3] KVM: arm64: tracing: add ftrace dependency

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Selecting CONFIG_TRACE_REMOTE causes a build time warning when FTRACE
is disabled:

WARNING: unmet direct dependencies detected for TRACE_REMOTE
  Depends on [n]: FTRACE [=n]
  Selected by [y]:
  - NVHE_EL2_TRACING [=y] && VIRTUALIZATION [=y] && KVM [=y] && NVHE_EL2_DEBUG [=y] && TRACING [=y]

Add this as another dependency to ensure a clean build.

Fixes: 3aed038aac8d ("KVM: arm64: Add trace remote for the nVHE/pKVM hyp")
