MFC r330667: asmc: update temperature sensor name/description

PR: 225911
Submitted by: Trev

MFC r273733, r273740 and r273773:

The SYSCTL data pointers can come from userspace and must not be
directly accessed. Although this will work on some platforms, it can
throw an exception if the pointer is invalid and then panic the kernel.

Add a missing SYSCTL_IN() of "SCTP_BASE_STATS" structure.

Give device_printf format string to pacify clang warning.

This isn't functionally identical. In some cases a hint to disable
unit 0 would in fact disable all units.

This reverts r241856

Now that device disabling is generic, remove extraneous code from the
device drivers that used to provide this feature.

Add support for MacBook Air. (not tested)

Obtained from: mactel-linux

Match the Mac Pro with 8 cores. This machine reports 35 temperature
sensors and some fans.
As I don't own this machine, I could not test this patch.

Obtained from: applesmc Linux driver.

Don't call acpi_disabled() because we are not part of the acpi.ko
module. Instead, use resource_disabled() that doesn't depend on any
module.

Style nit. No functional change.

Actually, I was looking at the wrong Linux .c file. Set INIT2 to its
previous value.
While there, lower the delay for the misterious key.

* Add missing #else in the #ifdef DEBUG section.
* Fix the login in asmc_init().
* Change the INIT2 constant to reflect the same change in the Linux driver.

"Prettyfy" numbers in hexadecimal. No functional change.

The SMC is represented on the acpi tables, so we can completely remove
dependency on isa. We are now an acpi child.

Also:
* Add compile time debugging activation
* Increase the delay for the SMS init flag.

Move INTR_FILTER from opt_global.h to its own header.

Move ASMC_FAN_FUNCS in the Macmini structure declaration one line up
so that this macro expands in the right place.

Driver for the Apple System Management Console (SMC). This hardware is
present on the MacBook, MacBook Pro, and Intel MacMini.

This driver exports information via sysctl in its private sysctl tree
dev.asmc.*. You can get information about temperatures, fan speeds, the
keyboard light sensor and the Sudden Motion Sensor (SMS).
The SMS is very useful to park the disk heads when the laptop is
moved. Basically, the SMS is setup so that, under movement, we get an
interrupt on irq 6 and a devd notification is sent.
