    da146x: hal_flash: Fix rdid issue on Gigadevice
    
    This patch moves the set manual mode and adds a busy status check before
    executing the read rdid qspi command.  On gigadevice flash devices, the read
    rdid would fail intermittently due to the device not being ready for the
    command.
