Accessiblity: speakup_ltlk: specifying the default driver parameters among the module params 

This is an enhancement which allows to specify the default driver
parameters among the module parameters.

Adding default variables to the speakup_ltlk module
allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:
