> In all the ZynqMP boards dts files tx-buswidth is by default set 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 in ZynqMP boards dts files. This would enable
> the spi-nor framework to issue 1-4-4 write commands instead of 1-1-1. This
> will increase the tx data transfer rate, as now the tx data will be
> transferred on four lines instead on single line.
