    mtd: spi-nor: aspeed: remove dummies from keep mask
    
    There is no need to keep the dummy bytes in the control register if
    the command mode is not kept also. This could lead to an inconsistent
    setting : normal read mode (command 0x3) and dummy bytes. It is to be
    noted that the HW allows such a configuration.
