interconnect: qcom: bcm-voter: Use enable_maks for keepalive voting

BCMs with an enable_mask expect to only have that specific value written
to them. The current implementation only works by miracle for BCMs with
enable mask == BIT(0), as the minimal vote we've been using so far just
so happens to be equal to that.

Use the correct value with keepalive voting.
