[U-Boot] [dm/next PATCH v1] dm: qspi fix claim bus and release bus

[Peng Fan]

For fsl_qspi_claim_bus and fsl_qspi_release_bus, the input parameter
"struct udevice *dev" represents device: "qspi[x]: qspi@[address] {...}".
Since "dev" already represents the qspi controller, use its parent to
get platdata and get 'priv' is wrong.

After applying this patch, qspi flashes can be correctly probed.
