[PATCH 2/3] arm64: dts: qcom: Add Eliza-specific PM7750BA dtsi

On Eliza, the SPMI arbiter supports multiple bus masters, requiring
explicit selection of the master for each PMIC.

The existing PM7750BA dtsi does not provide a way to describe this,
so introduce an Eliza-specific variant with the appropriate bus
configuration.

This duplication is required due to hardware differences in how the
SPMI bus is exposed on this platform.
