Subject: [PATCH] Accessiblity: speakup: 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 a default variables to the speakup_soft module
allows to easily set that at boot, rather than
setting the sys variables after boot.
More details can be found here:
