FogBugz #593535: stmmac: resolve smc related boot crash for ARMv7

Fix previous commit e8c95776cfce ("FogBugz #577927: stmmac: Add SMC
support for EMAC System Manager register")

The #ifdefs that check for SMC are insufficient, since currently only
Stratix10 has the trusted firmware that services these specific SMC calls.
Other ARMv7 platforms will crash at the first arm_smccc_smc() call. Fix
this by adding one additional check to allow the kernel boot properly on
other ARMv7 platforms.
