of/fdt: Fix incorrect use of dt_root_addr_cells in early_init_dt_check_kho()

Browse source

[ Upstream commit c85da64ce2 ]

When reading the fdt_size value, the argument passed to dt_mem_next_cell()
is dt_root_addr_cells, but it should be dt_root_size_cells.

The same issue occurs when reading the scratch_size value.

Use a helper function to simplify the code and fix these issues.
