[PATCH 1/2] spi: spi-uclass: Fix dm_spi_claim_bus()

[Hironori KIKUCHI]

When dm_spi_claim_bus() claims a bus, sometimes plat->mode and/or
plat->max_hz have not been copied to the priv object yet. This can lead
to an SPI bus malfunction.

To fix this, use the object returned by dev_get_parent_plat() instead,
which is set by spi_slave_of_to_plat() on spi_child_post_bind().
