hw/riscv/boot.c: consolidate all kernel init in riscv_load_kernel()

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

Let's fold everything inside riscv_load_kernel() to avoid code
repetition. To not change the behavior of boards that aren't calling
riscv_load_init(), add an 'load_initrd' flag to riscv_load_kernel() and
allow these boards to opt out from initrd loading.
