arm64: zynqmp: Set qspi tx-buswidth to 4

Browse Source 
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.
