ARM: dts: msm: Mark PMIC QUPs as critical clock devices for BLAIR

To prevent deadlocks between the clock and regulator frameworks,
the QUP clocks used by I2C-connected PMICs must be enabled all
the time and not registered with the clock framework. Skipping
the registration short-circuits the I2C device's clock calls such
that they return success before grabbing the clock locks. Achieve
this behavior by setting GCC's qcom,critical-devices property.
