mfd: t7l66xb: Drop platform disable callback

None of the in-tree instantiations of struct t7l66xb_platform_data
provides a disable callback. So better don't dereference this function
pointer unconditionally. As there is no user, drop it completely instead
of calling it conditional.

This is a preparation for making platform remove callbacks return void.
