This patch is about some noticable bugs which was made by no reason.
1. In rs690_cmn.c, mask the lower 4 bits of the BAR3. No doubt, right?
2. In rs690_pcie.c,
  (1) Obviously, the mask should be 0xF, and bit 19 should be set to 1 (in comment).
      In rpr 5.10.2, step 2, step 2.1 & step 2.6
  (2) The dynamic buffer allocation is enabled by setting bit 11 of PCIEIND: 0x20,
      instead of PCIEIND_P: 0x20.
      In rpr 5.10.2, step 5. Dynamic Slave CPL Buffer Allocation
