Update EfiAcpiResetSystem() to match function prototype for EFI_RESET_SYSTEM
Add CpuDeadLoop() in all paths, so EfiAcpiResetSystem() can never return to be compliant with UEFI Spec, even when ASSERT() statements are disabled.
Change DEBUG() messages from EFI_D_ERROR to DEBUG_INFO because they are not error messages.
Simplify implementation from 4 files down to 2 files.
Use IoAndTheOr16() and MmioAndTheOr16() instead if IoRead/Write16() and MmioRead/Write16()
