ALSA: emu10k1: compactize E-MU routing source arrays

Use macros to avoid duplication. Arguably, this is somewhat less
legible, but future additions would grow this part of the file to
completely unmanageable dimensions.
The EMU*_COMMON_TEXTS macros will save duplication in a future commit;
I pulled them ahead to reduce churn.

While rewriting the tables anyway, rearrange them such that each card's
strings and registers are adjacent.

Also, add some static asserts to verify that the array sizes match.
