From: Pankaj Bansal <pankaj.ban...@nxp.com>
The SwapMmio** APIs are supposed to be called indirectly via
GetMmioOperations** APIs.
Therefore, remove the SwapMmio** APIs from IoAccessLib.h and make
these APIs STATIC to IoAccessLib.c, so that no accidental call can
be made to these.
Signed-off-by: Pankaj Bansal <pankaj.ban...@nxp.com>

Notes:
V4:
- Use GetMmioOperations in place of GetMmioOperations32
- Use MMIO_OPERATIONS in place of MMIO_OPERATIONS_32
V3:
- New commit
