Remove the hardcoded .valid_modes_mask and .valid_ops_mask for
each regulator from the twl driver and let the boards pass it.

Please update this changelog - as I said in reply to your previous
posting this isn't actually hardcoding anything, it's dropping things
from the constraints which the hardware doesn't support.

Looks like I completely missed the "&=" and your comment
on the previous posting. Looking at it now, seems to me
this patch is just un-necessary and what the driver seems
to be doing (preventing users from setting flags which the
hardware does not support) seems perfectly fine.
I will just go ahead and drop this patch.
