Patch 8d03c42d38d1 ("ArmPkg: ArmFfaLib: Update FF-A direct message
to support 18 registers") calls SMCCC_VERSION by default during
FF-A initialization even if the SMC conduit is not enabled. This
leads to sending malformed FF-A versions if the SVC conduit is
used instead.
This is observed for example when using an SPMC@EL-1 (e.g. rust-spmc)
which receives the FF-A message via an SVC call and interprets
SMCCC_VERSION as an FF-A Function ID and subsequently fails to
handle it.
Since 18-register support is only support with FF-A >= 1.2, replace
SMCCC_VERSION check with FF-A version check
