realtek_mst_i2c_spi.c: Use one variable to store raw parameter values

Currently, each programmer parameter has their own temp variable to
store their raw value into it. That's not needed since these variables
are only used for a short time to do some configuration and stay unused
then. Thus, use only one variable for all of them.
