sbi: mpxy: define INVALID_ADDR using unsigned long width
INVALID_ADDR is used as an all-ones physical address sentinel.
Using -1U only guarantees 32-bit width, so on platforms where
unsigned long is wider it may not expand to all ones after assignment.
Use -1UL so the conversion to unsigned long preserves an all-ones
bit pattern across supported widths.
