tools: zynqmp_psu_init_minimize: Remove low level uart settings
There is no reason to do serial initialization. Uart driver does it
already based on DT. Good effect is that it is clear which interface is
console.
The resulting change was done in past by commit 84d2bbf082fa ("arm64:
zynqmp: Remove low level UART setting").
