clk: imx: imx6sx: remove the SET_RATE_PARENT flag for QSPI clocks

There is no dedicate parent clock for QSPI so SET_RATE_PARENT flag
should not be used. For instance, the default parent clock for QSPI is
pll2_bus, which is also the parent clock for quite a few modules, such
as MMDC, once GPMI NAND set clock rate for EDO5 mode can cause system
hang due to pll2_bus rate changed.
