Move remaining definitions and declarations from include/linux/bootmem.h
into include/linux/memblock.h and remove the redundant header.
The includes were replaced with the semantic patch below and then
semi-automated removal of duplicated '#include <linux/memblock.h>

Remove bootmem bitmap initialization and replace reserve_bootmem() with
memblock_reserve().

All we have to do is to enable memblock, the generic FDT code will take
care of the rest.

Now that the DT core code handles bootmem arches, we can remove the nios2
specific early_init_dt_alloc_memory_arch function.

As of commits d8f347ba35cf ("nios2: enable earlycon support"),
0dcc0542a006 ("serial: altera_jtaguart: add earlycon support") and
4d9d7d896d77 ("serial: altera_uart: add earlycon support"), the nios2
architecture and the altera_uart/altera_jtaguart drivers support
earlycon. Thus, the custom early console implementation for nios2 is no
longer necessary to get early boot messages. Remove it and rely fully on
earlycon support.

Make sure to reserve the boot memory for the flattened device tree.
Otherwise it might get overwritten, e.g. when initial_boot_params is
copied, leading to a corrupted FDT and a boot hang/crash:
bootconsole [early0] enabled
Early console on uart16650 initialized at 0xf8001600
OF: fdt: Error -11 processing FDT
Kernel panic - not syncing: setup_cpuinfo: No CPU found in devicetree!
---[ end Kernel panic - not syncing: setup_cpuinfo: No CPU found in devicetree!

nios2 builds fail with the following build error.
arch/nios2/kernel/prom.c: In function 'early_init_dt_scan_serial':
arch/nios2/kernel/prom.c:100:2: error:
implicit declaration of function 'fdt_translate_address'
Commit c90fe9c0394b ("of: earlycon: Move address translation to
of_setup_earlycon()") replaced fdt_translate_address() with
of_flat_dt_translate_address() but missed updating the nios2 code.
Fixes: c90fe9c0394b ("of: earlycon: Move address translation to of_setup_earlycon()")
