spi: spi-uclass: Add new spi_get_bus_and_cs() implementation

Browse source 
Move legacy spi_get_bus_and_cs() code to _spi_get_bus_and_cs().

Add new spi_get_bus_and_cs() implementation which rely on DT
for speed and mode and don't need any drv_name nor dev_name
parameters. This will prepare the ground for next patch.

Update all callers to use _spi_get_bus_and_cs() to keep the
same behavior.
