[PATCH v5 5/5] hw/ssi: xilinx_spips: Remove DMA related dead codes from zynqmp_spips

[Bin Meng]

From: Xuzhou Cheng <xuzhou.cheng@windriver.com>

Now that the Xilinx CSU DMA model is implemented, the existing
DMA related dead codes in the ZynqMP QSPI are useless and should
be removed. The maximum register number is also updated to only
include the QSPI registers.
