Min Xu 6b27c11690 OvmfPkg: Check Tdx in QemuFwCfgPei to avoid DMA operation ... RFC： https://bugzilla.tianocore.org/show_bug.cgi?id=3429 If TDX is enabled then we do not support DMA operation in PEI phase. This is mainly because DMA in TDX guest requires using bounce buffer (which need to allocate dynamic memory and allocating a PAGE size'd buffer can be challenge in PEI phase).
