eal: replace unsigned -1 with unsigned maximums

Use UINT64_MAX and UINT32_MAX instead of -1 or ~0 literal variations
of different explicit widths when creating masks and sentinel values.

Some compilers generate a warning when applying a '-' to an unsigned
literal so avoid this by initializing with unsigned preprocessor
definitions where appropriate.
