arm64: zynqmp: Set qspi tx-buswidth to 4

Amit Kumar Mahapatra · michalsimek · commit 1d831cade718 · 2023-06-05T13:15:02.000+02:00
All ZynqMP boards are setting up tx-buswidth to 1. Due to this the framework only issues 1-1-1 write commands to the GQSPI driver. But the GQSPI controller is capable of handling 1-4-4 write commands, so updated the tx-buswidth to 4. Using all 4 lines will increase the tx data transfer rate, as now the tx data will be transferred on four lines instead on single line.
