ARM: PL08x: fix fill_bytes calculation
The number of bytes we want to fill into any LLI is the minimum of:
- number of bytes remaining in the transfer
- number of bytes we can transfer in a single LLI
- number of bytes we can transfer without overflowing the source boundary
- number of bytes we can transfer without overflowing the destination boundary
The minimum of the first two is already calculated (target_len). We
limit the boundary calculations to this number of bytes, which will
then give us the number of bytes we can place into this LLI.
