staging: comedi: drivers: re-do PLX PCI 9080 DMADPRx register values
Replace the existing macros in "plx9080.h" that define values for the
DMADPR0 and DMADPR1 registers. (A little-endian version of the register
value is also placed in the `next` member of `struct plx_dma_desc`.)
Use the prefix `PLX_DMADPR_` for the macros. Make use of the `BIT(x)`
and `GENMASK(h,l)` macros to define the values.
