ARM: dts: msm: add a CX, MX and MMCX Turbo level proxy request for Lahaina

Browse source 
Add proxy-consumer properties to the VDD_MMCX rpmh-regulator
device node so that VDD_MMCX is kept enabled starting from
early in the application processor's boot sequence.  This
avoids issues when accessing multimedia clock controller
registers at initialization time.

Additionally, add proxy-consumer properties to the VDD_CX and
VDD_MX device nodes to avoid potential issues caused by a
clock voting for a lower voltage level than what is physically
required by a clock that is initialized at a later point.
