Subject: [PATCH] ARM: ux500: update V-INTCORE constraints

Update V-INTCORE regulator constraints to allow voltage and
configuration changes from consumer drivers.

Hi Linus,

this patch adds the regulators bits I'm missing for ux500-musb patches.
Without this I just get a runtime warning like:

V-INTCORE: operation not allowed

but the driver works anyway and there are no build dependencies, so I
think this can safely go in the arm-soc tree on its own, and the whole
thing should work happily in -next.

Thanks,
Fabio
