[parisc-linux] lasi Serial support

[Grant Grundler]

Hi all,
I just submitted another change to drivers/gecko/lasi.c after reviewing
the code and noting the IMR was being written twice in a row.

But I mainly write to question the location of LASI serial port code.
I don't know if it's "right" to have this code in lasi.c.  I'd like
to understand if it is and why. I'm confused because Lasi SCSI support
is in lasi7xx.c.  Is it reasonable to create a lasi_RS232.c (or whatever)?

And I'm thinking keeping the lasi.c/h files smaller is a good thing.
One can also modularize the support better (ie put the ifdef in the
Makefile instead).  Other thoughts on this?
If it's the "right" thing to do, any volunteers?

thanks,
grant
