    boards/risc-v/qemu-rv: Add missing section on `ld-nuttsbi.script`
    
    Fix an issue regarding the `rv-virt:nsbi` defconfig, which wasn't
    booting properly because `sbi_set_mtimecmp` failed to get the
    mtimecmp's register address when evaluating `g_mtimecmp`. This
    variable, which should be located at the `.noinit` section, wasn't
    being set accordingly by the linker script, ending up on `bss
    section which is zero-initialized, overwriting its value previously
    set by `sbi_init_mtimer`.
