MdePkg:simplify Fifo API in BaseIoLibIntrinsic

Browse Source 
Simplify IoRead/WriteFifo implement by repeatedly
calling IoRead/Write in the C code.
This can avoid calling assembly code to use string
I/O instructions. With this change Ia32/IoFifo.nasm
and X64/IoFifo.nasm can be removed. Then the source
files for IA32 and X64 are the same.
