sys: Automated cleanup of cdefs and other formatting

no-longer-needed sys/cdefs.h includes as well as now-empty
blank lines in a row.

Remove /^#if.*\n#endif.*\n#include\s+<sys/cdefs.h>.*\n/
Remove /\n+#include\s+<sys/cdefs.h>.*\n+#if.*\n#endif.*\n+/
Remove /\n+#if.*\n#endif.*\n+/
Remove /^#if.*\n#endif.*\n/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/types.h>/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/param.h>/
Remove /\n+#include\s+<sys/cdefs.h>\n#include\s+<sys/capsicum.h>/

sys: Remove $FreeBSD$: one-line .c pattern

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

tpm: Remove unused variables.

All of the legacy config stuff in tpm seems broken. Nothing ever sets
tpm_enabled to a non-zero value and the legacy bits expect tpm_enabled
to be set to the base IO port address (I think).

unifdef -D__FreeBSD__ to remove the OpenBSD support

OpenBSD never accepted this driver, and instead wrote their
own minimal one (sys/dev/acpi/tpm.c for suspending the device).

tpm: clean up empty lines in .c and .h files

Remove dead code.
The #ifdef __FreeBSD__ section within the OpenBSD tpm_attach() implementation
can never be active.

Consistently use `device_t`

Several files use the internal name of `struct device` instead of
`device_t` which is part of the public API. This patch changes all
`struct device *` to `device_t`.

The remaining occurrences of `struct device` are those referring to the
Linux or OpenBSD version of the structure, or the code is not built on
FreeBSD and it's unclear what to do.

sys/dev: minor spelling fixes.

Most affect comments, very few have user-visible effects.

In sys/dev/tpm/tpm.c, #if 0 an unused static function.
