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

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

arm: Rename hdmi_if.m to crtc_if.m

There is nothing hdmi related in this interface, it's just a generic interface
for crt controller so rename it.
This also remove the 'hdmi' device used in arm kernel config. 'vt' now controls
if we build this interface (sc(4) isn't supported on arm).

arm ti: Remove unused devclass arguments to DRIVER_MODULE.

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

Remove use of intr_config_hook from the am335x_pmic and tda19988 drivers.
Long ago this was needed, but now low-level i2c controller drivers cleverly
defer attachment of the bus until interrupts are enabled (if they require
interrupts to function), so that every i2c slave device doesn't have to.

Include eventhandler.h in more compilation units

This was enumerated with exhaustive search for sys/eventhandler.h includes,
cross-referenced against EVENTHANDLER_* usage with the comm(1) utility. Manual
checking was performed to avoid redundant includes in some drivers where a
common os_bsd.h (for example) included sys/eventhandler.h indirectly, but it is
possible some of these are redundant with driver-specific headers in ways I
didn't notice.

(These CUs did not show up as missing eventhandler.h in tinderbox.)

Somewhat improve HDMI event API

- Pass device_t for HDMI framer as an argument for event hook
- Use #define for event values, instead of opaque (and unused) 0

Move all HDMI-related stuff to hdmi_if.m, hdmi.h is not required

Fix parsing of I2C addresses properties in fdt data. I2C address is
represented in 7-bits format in DT files, but system expect it in 8-bit
format. Also, fix two drivers that locally hack around this bug.
