- Remove #ifdefs in favor of new is_cppi_enabled() macro.
 - Trim some tx-start logic, inlining it and removing MGC_{Read,Write}Csr16()
 - Remove remnant of bogus/non-existent host-side ISO bitfield.

For upstream merging, more such #ifdeffery still needs to be removed.

 - Add header needed for DaVinci build.
 - Remove some partially obsolete comments.
 - Cleaner and more reproducible host side VBUS handling, including
   waiting for it to fall after powerdown on rmmod.
 - Tighten up various state machine transitions and diagnostics

Plus removing some generic #ifdeffery.  The vbus updates make it work more like
the TUSB code, and the cleanups etc make upstream merging more practical.

When you're willing to trust the USB host not to commit certain errors, the
CPPI "rndis" RX mode can be used with the peripheral side g_ether driver.
(In other cases, rndis rx mode tends to misbehave _very_ rudely ...)

This patch adds a heuristic to detect when the safe scenario is likely, and
a module parameter to disable the heuristic in contexts when it's likely
to fail; for example, users of gadgetfs will likely need to disable it.

This gave about a 60% improvement in throughput with CDC Ethernet (!!) and a
slight reduction in CPU load.  That's measured with TTCP, which pushes a lot
of full size Ethernet frames and thus can see three IRQs per packet reduced
to just one, and also get I/O overlap when double buffering packets.  That is,
net 10 MByte/sec sustained, using double buffering but no DMA transfer queues;
it's unclear why TX is still just 6 MByte/sec.

General update of the board file for Palm Tungsten E. Registers the
platform devices contained in the PDA (ROM chip, keypad, infra-red)
and updates the configuration for USB and MMC, whose config values
were previously guessed in most cases due to lack of documentation
(and now are confirmed by a number of users). Macros for GPIO pins are
moved to a file in include/asm-arm/arch-omap.
