This patch updates the register offsets in the AXI4 data path
as per latest IP version(v4.1).
The addresses are changed to accommodate increased data width.
With old address map and increased data width user had to generate AXI4 unaligned transactions.
Therefore, the address map was changed for ease of use in the IP.

This does following things
1. For lees than 8 byte requests, done in IO mode.
2. One dummy GenFifo entry at the end in case of IO mode.
3. used memcpy while filling TxFifo.

The recommendation from design is to have bus width of dummy entry =
bus width of address phase (whether this is 1, 2 or 4).
This code will remain same irrespective of QEMU. Hence change the comment.

This patch does following things.
1. Added Cache support.
2. Modified TXD_DEPTH to 64.
3. Enabled RXEMPTY interrupt.
4. Modified the param passed to XQspiPsu_ReadRxFifo API to
RxThreshold*4, since it is expecting number of bytes to read.
5. Used Qspipsu Instance buffers in Interrupt handler rather
than Msg buffers.

Removed the configuration of DMA Buffer Boundary register in WriteSpareBytes API
as the driver uses oob size as pkt size and thus configuring DMA Buffer
Boundary Register has no effect.

Since the check for the block to have reached the end block was at the end of the loop,
thus assert call triggering could happen if the block crosses the max block limit,
making the driver to hang. Thus to fix the triggering of assert call,
the check for the block to have reached the max block is being done at the start of
the loop in XNandPsu_CalculateLength function.
The u32 typecasting for the variable OffsetVar has been removed and the data type for
the variable TempLen has been changed to u64 as for higher block numbers the value for
these variables will require u64 datatype otherwise corrupted value will get stored
which will lead to wrong calculation of block.

Removed the workaround for qemu in driver code as qemu now supports

Modified number of bytes to be read for bbt in oob and bbt with signature
and version for no oob option. This change is done kept in mind that it
should support flashes with small page size as well.
