Use ioremap to obtain access to registers instead of using static
mappings. This reduces the number of users of the static mappings, which
will eventually allow them to be removed.
Note that on Tegra30, the number of register "banks" will decrease to 2,
and the packing of specific bits into registers will change significantly.
That's why this change adds the "*_bank" fields to the pingroup tables,
rather than implementing some more hard-coded scheme.
Also, completely remove the implementation of suspend/resume; Tegra doesn't
yet support suspend/resume, and the implementation is complex for the
general pinmux driver:
* Not all registers are used within each bank, so we probably shouldn't
just iterate over every register in the bank, and save/restore it,
since that would mean touching undefined registers.
* Registers are shared between pingroups, so we can't simply iterate over
each pingroup, and save/restore the registers it uses.
It'd probably be best have probe() calculate a bitmask of actually-used
registers for each bank, and have suspend/resume iterate over those
bitmaps.
Oh, and Real Soon Now, I should be looking into converting this driver to
the new pinmux/pinctrl subsystem, so I didn't want to put too much work
into the current incarnation.
v2: s/space/bank/ to match comments on reg_* fields in pinmux.h.
Re-order bank/reg parameters to pg_readl/pg_writel.

A new Tegra pinmux platform device will also be added.

Rather than marking the mach/gpio.h header files which want to use the
trivial GPIOLIB implementation, mark those which do not want to use it
instead. This means that by default, you get the trivial implementation
and only have to do something extra if you need to. This should
encourage the use of the trivial default implementation.
As an additional bonus, several gpio.h header files become empty.
