[PATCH 03/10] hw/riscv/sifive_u.c: simplify create_fdt()

[Daniel Henrique Barboza]

'cmdline' isn't being used. Remove it.

A MachineState pointer is being retrieved via a MACHINE() macro calling
qdev_get_machine(). Use MACHINE(s) instead to avoid calling qdev().

 'mem_size' is being set as machine->ram_size by the caller. Retrieve it
via ms->ram_size.
