staging: comedi: drivers: re-do macros for PLX PCI 9080 LASxRR values
Rename the macros for the PLX PCI 9080 LAS0RR and LAS1RR registers in "plx9080.h", using the prefix `PLX_LASRR_`. Make use of the `BIT(x)` and `GENMASK(h,l)` macros to define the values. Define a macro `PLX_LASRR_PREFETCH` for the "prefetchable memory" bit in this register, and define a macro `PLX_LASRR_MLOC_MASK` to mask the PCI memory location control bits.
