[PATCH v3 20/23] interconnect: qcom: icc-rpm: Fix bucket number

[Konrad Dybcio <konrad.dybcio@linaro.org>]

SMD RPM only provides two buckets, one each for the active-only and
active-sleep RPM contexts. Use the correct constant to allocate and
operate on them.

This will make the qcom,icc.h header no longer work with this driver,
mostly because.. it was never meant to! The commit that introduced
bucket support to SMD RPM was trying to shove a square into a round
hole and it did not work out very well. That said, there are no
active users of SMD RPM ICC + qcom,icc.h, so that doesn't hurt.

Fixes: dcbce7b0a79c ("interconnect: qcom: icc-rpm: Support multiple buckets")
