There are references in the code to 256 sources, so I tested it with 256 aplays,
of which the first and last with real data and the rest playing /dev/zero .
Also increase amount of page tables, so the default aplay size works.

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.

Remove the limitation of PAGE_SIZE to be 4k by defining the own
page size and macros for 4k. 8kb page size could be natively supported,
but it's disabled right now for simplicity.
Also, clean up using upper_32_bits() macro.
