[PATCH v4 10/11] hw/riscv/boot.c: introduce riscv_load_kernel_and_initrd() |

The microchip_icicle_kit, sifive_u, spike and virt boards are now doing
the same steps when '-kernel' is used:
- execute load_kernel()
- load init_rd()
- write kernel_cmdline in the fdt
Let's fold everything inside riscv_load_kernel() to avoid code
repetition. Every other board that uses riscv_load_kernel() will have
this same behavior, including boards that doesn't have a valid FDT, so
we need to take care to not do FDT operations without checking it first.
Since we're now doing way more than just loading the kernel, rename
riscv_load_kernel() to riscv_load_kernel_and_initrd().
