Change fdtbus_register_i2c_controller() to directly register the i2c_tag_t,
rather than the device and a set of functions (the only of which was to
return the i2c_tag_t anyway).  Previously, this assumed only a single
i2c controller node per device_t, which is not true with an i2c mux.

Use a separate lock (not the i2c bus lock) to synchronize with the
interrupt handler.  This in all liklihood fixes a deadlock bug that
necessitated forcing I2C_F_POLL in tegra_i2c_exec() (someone who has
the hardware should test removing that line).

Also includes the changes for:

Cleanup i2c bus acquire / release, centralizing all of the logic into
iic_acquire_bus() / iic_release_bus().  "acquire" and "release" hooks
no longer need to be provided by back-end controller drivers (only if
they need special handling, e.g. powering on the i2c controller).
This results in the removal of a bunch of rendundant code from each
back-end controller driver.

Assert that we are not in hard interrupt context in iic_acquire_bus(),
iic_exec(), and iic_release_bus().

Changes since revision 1.20: +9 -9 lines
Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

If we don't get informed (via device properties) of child I2C devices,
don't assign an empty array to iba.iba_child_devices, as it will prevent
indirect configuration of the I2C bus from occurring.

Tested on Raspberry Pi (bcm2835), identical logical fix replicated
(and compile-tested) elsewhere.
