ALSA: ctxfi - fix PTP address initialization

commit 21956b61f594f7924d98240da74bc81c28601fa9 upstream.

After hours of debugging, I finally found the reason why some source
and runtime combination does not work. The PTP (page table pages)
address must be aligned. I am not sure how much, but alignment to
PAGE_SIZE is sufficient. Also, use ALSA's page allocation routines
to ensure proper virtual -> physical address translation.
