of this the TX_DONE
is the 25 bit in the status register.

The existing macro works for the following scenarios
1) S3C6410 all channels
2) S5PC100 all channels

The FIFO data level supported in the above SoCs 64 bytes
on all the channels. Because of this the TX_DONE is the 21 bit
in the status register.

So when we use the existing macro for the non-working SoCs
it is not anding with the TX_DONE bit for transmission status check.
