This converts the zynq spi driver to use the driver model.
Minimal functional changes like using meaningful name on structure members wrt mainlined dm spi drivers.
- input_hz -> frequency
- req_hz -> freq
- base -> regs

I see you remove this in a latest patch.

if (bus->seq) return (struct zynq_spi_regs *)ZYNQ_SPI_BASEADDR1; else return (struct zynq_spi_regs *)ZYNQ_SPI_BASEADDR0;}
