ssb: update reject bit for Target State Low

ssb: update reject bit for Target State Low

My 14e4:4315 is SSB_IDLOW_SSBREV_26:
read32 0xfaafcff8 -> 0x600422d5
My 14e4:4328 is SSB_IDLOW_SSBREV_24:
read32 0xfaafcff8 -> 0x400422c5
My 14e4:432b is SSB_IDLOW_SSBREV_26 again:
read32 0xfaafcff8 -> 0x600422d5

For all of them wl driver is using 0x2 reject bit:
write32(0xf98) <- 0x00010002
So it seems SSB 2.3 is the exception using another bit.
