spi: spi-fsl-dspi: Re-use one volatile regmap for both device types
max_register overrides anything in the volatile ranges, so we can get
away with sharing the same one for both types. In a later commit we'll
add more devices so this avoids adding even more duplication. Also
replace the max_register magic numbers with their register definitions
so it's clearer what's going on.
No functional changes.
