Ck802 smart mode should not be treated as ck801.
It do only allocate r0-r8 registers like ck801,
but support 32-bits intructions.
This bug will cause ICE when compiler pr43164.c for ck802 big-endian,
/src/gcc/gcc/testsuite/gcc.c-torture/compile/pr43164.c:16:1: error: insn does not satisfy its constraints:
(insn 48 28 30 2 (set (reg:SI 0 a0 [230])
(ior:SI (reg:SI 2 a2 [222])
(ashift:SI (const_int 1 [0x1])
(const_int 24 [0x18])))) "/src/gcc/gcc/testsuite/gcc.c-torture/compile/pr43164.c":15:10 224 {smart_bseti}
