commit "dm: spi: Avoid setting the speed with every transfer"

Hi I'm wondering how commit 60e2809a84 (dm: spi: Avoid setting the speed with every transfer) works. AFAIU, the currently selected speed is a property of the SPI master, so suppose we have two slaves, A which has max_hz = 10MHz and B which has max_hz = 20MHz. Now suppose we do transfers to A,
