pmdomain: qcom: rpmhpd: Add missing MXC and MMCX power domains for Eliza

MXC and MMCX were initially omitted as they were believed to have no
consumers, and they were not present downstream either.

The Iris video codec requires these power domains, so add MXC and MMCX
along with the MXC_AO and MMCX_AO.
