Takashi Iwai 6974f8ad44 ALSA: pci: Avoid non-standard macro usage
Pass the device pointer from the PCI pointer directly, instead of a
non-standard macro.  The macro didn't give any better readability.

Sudip Mukherjee 0cae90a96c ALSA: ctxfi: pr_* replaced with dev_*
pr_* macros replaced with dev_* as they are more preffered over pr_*.
each file which had pr_* was reviewed manually and replaced with dev_*.
here we have actually used the various snd_card which was added to some
structures of ctxfi via a previous patch of this series.

in the ctvmem.c file we have passed a reference of ct_atc as an
argument to get_vm_block function so that it can be used from
dev_*.

since dev_* will print the device information , so the prefix of
"ctxfi" from the various pr_* were also removed.

Sudip Mukherjee e720b82027 ALSA: ctxfi: prink replacement
as pr_* macros are more preffered over printk, so printk replaced with corresponding pr_err and pr_alert
this patch will generate a warning from checkpatch for an unnecessary space before new line and has not been fixed as this patch is only for printk replacement.

Jaroslav Kysela 21956b61f5 ALSA: ctxfi - fix PTP address initialization
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.
