palm_bk3710: those registers/bitfields don't exist

Bugfixes noted by checking the code against the controller
documentation (TI document number SPRUE21):

 - Remove declarations for eight non-existent registers (!);
   and remove accesses to two of them.

 - Remove access to various non-existent bitfields in some of
   the registers which *do* exist (those fields must-be-zero).

 - Provide comment to replace bogus reset logic (removed above,

   help; this driver doesn't currently know about that.

lookup of the PIO timings.

palm_bk3710: UDMA performance fix

Fix UDMA throughput bug:  tCYC averages t2CYCTYP/2, but the code
previously assumed it was the same as t2CYCTYP.  (That is, it was
using just one clock edge, not both.)  Move the table's type
declaration so it's adjacent to the table, making it more clear
what those numbers mean.

On one system this change increased throughput by almost 4x: UDMA/66
sometimes topped 23 MB/sec (on a drive known to do much better).  On
another system it was around a 10% win (UDMA/66 up to 7+ MB/sec).

The difference might be caused by the ratio between memory and IDE
clocks.  In the system with large speedup, this was exactly 2 (as a
workaround for a rev 1.1 silicon bug).  The other system used a more
standard ratio of 1.63 (and rev 2.1 silicon) ... clock domain synch
might have some issues, they're not unheard-of.

in and tries to use TUNER_SET_TYPE, which went away a long time ago.

This patch removes all of this logic, as it should not be needed anymore

USB: musb: bugfixes for multi-packet TXDMA support

We really want to use DMA mode 1 for all multi-packet transfers;
that's one IRQ on DMA completion, instead of one per packet.

There is an important issue with such transfers, especially on
the host side:  when such transfers end with a full-size packet,
we must defer musb_dma_completion() calls until the FIFO empties.
Else we report URB completions too soon, and may clobber data in
the FIFO fifo when writing the next packet (losing data).

The Inventra DMA support uses DMA mode 1, but it ignores that
issue.  The CPPI DMA support uses mode 0, but doesn't handle
its TXPKTRDY interrupts quite right either; it can get stale
"packet ready" interrupts, and report transfer completion too
early using slightly different code paths, also losing data.

So I'm solving it in a generic way -- by adding a sort of the
"interrupt filter" into musb_host_tx(), catching these cases
where a DMA completion IRQ doesn't suffice and removing some
needlessly controller-specific logic.  When a TXDMA interrupt
happens and DMA request mode 1 is active, that filter resets
to mode 0 and defers URB completion processing until TXPKTRDY,
unless the FIFO is already empty.  Related filtering logic in
Inventra and CPPI code gets removed.

Since it should be competely safe now to use the DMA request
mode 1 for host side transfers with the CPPI DMA controller,
set it in musb_h_tx_dma_start() ... now renamed (and shared).

AFS: Guard afs_file_readpage_read_complete() definition with CONFIG_AFS_FSCACHE

If CONFIG_AFS_FSCACHE is not defined, the following warning is displayed when
fs/afs/file.c is compiled:

 fs/afs/file.c:111: warning: ‘afs_file_readpage_read_complete’ defined but not used

This occurs because all calls to this function are guarded by
CONFIG_AFS_FSCACHE.  Thus, guard its definition as well.
