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.

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.

If oob size is less than 64 bytes, ecc position should start from 0 position
of oob area, else should be at the end of the oob area.
Keeping ecc start position in alligned with the Linux nand base ecc layout.

QSPI HW doesn't actually care what the SPI mode is for the dummy phase
of flash commands. We have confirmed this with randomized testing.
However due to a core limitation of QEMU it is expected to match the
mode of the address phase for QEMU.
So since QEMU is the only platform that cares, set the dummy mode to
QEMUs expectation.

There is a bug wherein the DMA listening to RX empty status goes busy
if RX FIFO clear bit is set in the FIFO control register, even if there
is no transfer request. So switch to I/O mode always to clear RX FIFO and
restore the mode in the end.

Add an option to enable jumbo frames for zynqmp.
Add frame size and receive buffer length masks to instance so that they can

Ensure that the dma buffer boundary interrupt is disabled as driver
is using the contiguous buffer for the whole page size and enabling
this interrupt would cause failures if the buffer boundary is
configured for other values (not the page size)
