Update ADSP pil loader driver for SC7280 platforms.
Changes since V4:
-- Update halt registers description in dt bindings.
-- Update Memory sandboxing with proper APIs for resource
allocation and free.
Changes since V3:
-- Rename is_adsp_sb_needed to adsp_sandbox_needed.
-- Update sc7280 compatible name entry in sorted order.
-- Add smmu unmapping in error case and in adsp stop.
-- Revert converting sdm845 dt bindings to generic and
create new dt bindings for sc7280.
Changes since V2:
-- Generated patch with -M flag.
-- Add Clock property in dt bindings.
-- Add qcom,adsp-memory-regions property.
-- Add is_adsp_sb_needed flag instead of is_wpss.
-- Initialize is_adsp_sb_needed flag.
-- Remove empty proxy pds array.
-- Replace platform_bus_type with adsp->dev->bus.
-- Use API of_parse_phandle_with_args() instead of
of_parse_phandle_with_fixed_args().
-- Replace adsp->is_wpss with adsp->is_adsp.
-- Update error handling in adsp_start().
Changes since V1:
-- Change reg property maxItems to minItems and update description.
-- Fix typo errors.
