[PATCH 03/23] arm64: zynqmp: Set qspi tx-buswidth to 4

Michal Simek

From: Amit Kumar Mahapatra <amit.kumar-mahapatra@xilinx.com>

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.
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.
