spi/qspi: set correct platform drvdata in ti_qspi_probe()
The ti_qspi_remove() use the platform drvdata as a type of
struct ti_qspi, we should pass correct platform drvdata to
platform_set_drvdata() in ti_qspi_probe().

platform_set_drvdata was changed in the probe, so we need to
correspondingly change deferencing of qspi in runtime resume
path. Else, this will lead to a NULL dereference pointer.
Based on v3.13-rc3
