For abiv2 we couldn't use "trap 1" as user space bkpt in gdbserver, because
abiv2 is 16/32bit instruction set and "trap 1" is 32bit.
So we need a 16bit instruction as user space bkpt, and it will cause an illegal
instruction exception.
In kernel we parse the *regs->pc to determine whether to send SIGTRAP or not.

User could define the dtb instead of the one which is passed from
bootloader.
Sometimes for debug, we want to use a built-in dtb and then we needn't
modify bootloader at all.
