[PATCH 3/3] arm64: dts: sc7180: Add assigned-performance-states for i2c

[Rajendra Nayak <rnayak@codeaurora.org>]

qup-i2c devices on sc7180 are clocked with a fixed clock (19.2 Mhz)
Though qup-i2c does not support DVFS, it still needs to vote for a
performance state on 'cx' to satisfy the 19.2 Mhz clock frequency
requirement.

Use 'assigned-performance-states' to pass this information from
device tree, and also add the power-domains property to specify
the cx power-domain.
