Support Genesys Logic, Inc GL32xx Flash programming support

The Genesys Logic, Inc USB Memory Card Reader Controller devices
offers ISP (In System Programming) of their attached flash.

The protocl uses vendor SCSI/USB Mass Storage CBD commands exposing
the SPI Flash bus providing command sending and optimized read/write.

The protocol should be compatible with the GL32xx Memory Card Reader
devices, including devices with a custom VID/PID.

Only the tested GL3232 devices listed in the devs has been validated,
but the driver matches with all Genesys Logic, Inc mass storage
devices.
