[PATCH] phy: qcom-qmp-combo: Use regulator_bulk_data with init_load_uA for regulator setup

[Faisal Hassan]

Replace the custom qmp_regulator_data structure with the standard
regulator_bulk_data and use the init_load_uA field to set regulator
load during initialization.

This change simplifies the regulator setup by removing manual
allocation and load configuration logic, and leverages
devm_regulator_bulk_get_const() to automatically apply load settings
before enabling regulators.
