The GPTIMER TLDR register does not need to be written if the GPTIMER
is not in autoreload mode.  This is the usual case for dynamic tick-enabled
kernels.

Simulation data indicate that skipping the read that occurs as part of
the write should save at least 300-320 ns for each GPTIMER1 timer
reprogram.  (This assumes L4-Wakeup is at 19MHz and GPTIMER write
posting is enabled.)  Skipping the write itself probably won't have
much impact since it should be posted on the OCP interconnect.

Tested on 2430SDP and 3430SDP.

More conversion to the standard GPIO interfaces:  stop using
omap_set_gpio_direction() entirely, and switch over to the
gpio_direction_output() call.

Note that because gpio_direction_output() includes the initial
value, this change isn't quite transparent.

 - For the call sites which defined an initial value either
   before or after setting the direction, that value was used.

   When that value was previously assigned afterwards, this
   could eliminate a brief output glitch ... and possibly
   change behavior.  In a few cases (LCDs) several values
   were assigned together ... those were re-arranged to match
   the explicit sequence provided.

 - Some call sites didn't define such a value; so I chose an
   initial "off/reset" value that seemed to default to "off".

In short, files touched by this patch might notice some small
changes in startup behavior (with trivial fixes).

When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not
(and should not) be commonly used.

On omap24xx, INTCPS_SIR_IRQ_OFFSET bits [6:0] contains the current
active interrupt number.

However, on 34xx INTCPS_SIR_IRQ_OFFSET bits [31:7] also contains the
SPURIOUSIRQFLAG, which gets set if the interrupt sorting information
is invalid.

If the SPURIOUSIRQFLAG bits are not ignored, the interrupt code will
occasionally produce a bunch of confusing errors:

irq -33, desc: c02ddcc8, depth: 0, count: 0, unhandled: 0
->handle_irq():  c006f23c, handle_bad_irq+0x0/0x22c
