The MSM8917, MSM8937 and QM215 SoCs have VDDCX and VDDMD power domains
controlled in voltage level mode. Define the MSM8937 and QM215 power
domains as aliases because these SoCs are similar to MSM8917 and may
share some parts of the device tree.
Also add the compatibles for these SoCs to the documentation.

MSM8917 uses the SMPA2 and LDOA3 regulators provided by the PM8937 PMIC
for the VDDCX and VDDMX power domains in voltage level mode,
respectively. MSM8937 also uses this PMIC and the same regulators.
QM215 is typically paired with a PM8916 PMIC and uses its SMPA1 and
LDOA2 regulators in voltage level mode.
