Subject: riscv: mm: remove redundant parameter of create_fdt_early_page_table
From: Song Shuai <suagrfillet@xxxxxxxxx>
commit e4ef93edd4e0b022529303db1915766ff9de450e upstream.
create_fdt_early_page_table() explicitly uses early_pg_dir for
32-bit fdt mapping and the pgdir parameter is redundant here.
So remove it and its caller.
