Follow the pattern of other drivers and use aligned_s64 for the
timestamp. This will ensure the struct itself it also 8-byte aligned.

While touching this, convert struct mpr_chan to an anonymous struct
to consolidate the code a bit to make it easier for future readers.

I didn't pick up review tags on this one since removing the struct
definition is a biggish change compared to v1.
