Add support for the %pV format-specifier which allows printing a struct va_format. This is used by the Linux kernel for recursive printf() formatting and is needed by the ext4l filesystem driver. Add the struct to include/linux/printk.h to match the kernel location. Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <simon.glass@canonical.com>
