ArmVirtPkg/PrePi: Enable VFP before calling into C code
When building ArmVirtQemuKernel with CLANGDWARF (which does not require
a GCC workaround where -mgeneral-regs-only is needed to ensure
-mstrict-align works as expected), the C code invoked from the PrePi
startup code may contain instructions that access the FP/SIMD register
file. This means that the FP/SIMD must be enabled before making such
calls, and this is currently not the case. So fix that, by moving the
call to ArmEnableVFP() early into the asm startup code.
