have wrong with rt_kprintf ("%lx") and rt_kprintf ("%llx")

RT-Thread aarch64 rt_kprintf:

msh />_test
0xabcdef1234567890 %lx = 0x34567890
0xabcdef1234567890 %llx = 0x%lx
0xabcdef1234567890 %lx%lx = 0xabcdef1234567890

ubase %lx = 0x34567890
ubase %llx = 0x%lx
ubase %lx%lx = 0xabcdef1234567890

u64 %lx = 0x34567890
u64 %llx = 0x%lx

Linux x64 printf:

gui@DESKTOP-J4PRI2C:~$ ./main
0xabcdef1234567890 %lx = 0xabcdef1234567890
0xabcdef1234567890 %llx = 0xabcdef1234567890
0xabcdef1234567890 %lx%lx = 0xabcdef12abcdef1234567890

ubase %lx = 0xabcdef1234567890
ubase %llx = 0xabcdef1234567890
ubase %lx%lx = 0xabcdef12abcdef1234567890

u64 %lx = 0xabcdef1234567890
u64 %llx = 0xabcdef1234567890
u64 %lx%lx = 0xabcdef12abcdef1234567890

0xabcdef1234567890 %p = 0x0xabcdef1234567890
gui@DESKTOP-J4PRI2C:~$

%lx不能正确打印出64位的hex，需要将变量分高32位和低32位；%llx不能使用。

嗯 看来这个得修一下，你可以先用这个软件包打个补丁，安装上就能用：https://github.com/mysterywolf/rt_vsnprintf_full
