Stop passing around bootmem_base value.
For the calls to boot_relocate_fdt(), boot_get_cmdline(), and boot_get_kbd(), the value of bootmem_base is always obtained by calling getenv_bootm_low(). Since the value always comes from the same source, the calling signature for those functions can be simplified by making them call getenv_bootm_low() directly.
