ALSA: pci: Simplify with dma_set_mask_and_coherent()

Many PCI drivers still have two explicit calls of dma_set_mask() and
dma_set_coherent_mask().

Let's simplify with dma_set_mask_and_coherent().

ALSA:: ctxfi: cthw20k1: Replace mdelay() with msleep()

hw_pll_init(), hw_reset_dac() and hw_card_init() are never
called in atomic context.
They calls mdelay() to busily wait, which is not necessary.
mdelay() can be replaced with msleep().

ALSA: ctxfi: Fix the incorrect check of dma_set_mask() call

In the commit [15c75b09f8d1: ALSA: ctxfi: Fallback DMA mask to 32bit],
I forgot to put "!" at dam_set_mask() call check in cthw20k1.c (while
cthw20k2.c is OK). This patch fixes that obvious bug.

(As a side note: although the original commit was completely wrong,
it's still working for most of machines, as it sets to 32bit DMA mask
in the end. So the bug severity is low.)

ALSA: ctxfi: Fallback DMA mask to 32bit

Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit
architectures, and bails out if it fails. This causes a problem on
some platforms since the 64bit DMA isn't always guaranteed. We should
fall back to the default 32bit DMA when 64bit DMA fails.

ALSA: ctxfi: Simplify PM callbacks

This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801:
PCI core handles power state for us].

Since pci_set_power_state(), pci_save_state() and pci_restore_state()
are already done in the PCI core side, so we don't need to it doubly.

Also, pci_enable_device(), pci_disable_device() and pci_set_master()
calls in PM callbacks are superfluous nowadays, too, so get rid of
them as well.

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.

ALSA: ctxfi: sparse warning

fixed sparse warning of incorrect type (different address spaces) in
cthw20k1.c and cthw20k2.c which was being actually caused as mem_base
was of the type unsigned long.

Again as mem_base was previously unsigned long , so it required many
typecasts in the code to convert interger to pointer.

Now after giving the correct type of mem_base as void __iomem *
we can also remove those typecasts maintaining the same functionality
and logic of the code.

The name argument of request_irq() appears in /proc/interrupts, and
