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.
