Ovidiu Panait 741280e9ac spi: spi-uclass: Fix spi_claim_bus() speed/mode setup logic 
Currently, when different spi slaves claim the bus consecutively using
spi_claim_bus(), spi_set_speed_mode() will only be executed on the first
two calls, leaving the bus in a bad state starting with the third call.

This patch drops spi_slave->speed member and adds caching of bus
speed/mode in dm_spi_bus struct. It also updates spi_claim_bus() to call
spi_set_speed_mode() if either speed or mode is different from what the
bus is currently configured for. Current behavior is to only take into
account the speed, but not the mode, which seems wrong.

Fixes: 60e2809a84 ("dm: spi: Avoid setting the speed with every transfer")
