C-SKY: Fix patterns' condition for ck802 smart mode.

C-SKY: Fix patterns' condition for ck802 smart mode.

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,
