The OSPI module does not provide any hardware signal for busy or idle status. Software need to ensure that the OSPI module is idle before clocks can be shut off by reading the OSPI_CONFIG_REG[31] IDLE_FLD bit.
OSPI_PCLK and OSPI_HCLK share the same clock stop request/acknowledge and clock enable/acknowledge interface.
