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 kern

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/arm64 freescale: Remove unused devclass arguments to DRIVER_MODULE.

Add mode selection to iMX6 IPU driver

Add mode selection to iMX6 IPU driver

- Configure ipu1_di0 tob e sourced from the VIDEO_PLL(PLL5) and hardcode
frequency to (455000000/3)Mhz. This value, further divided, can yield
frequencies close enough to support 1080p, 720p, 1024x768, and 640x480
modes. This is not ideal but it's an improvement comparing to the only
hardcoded 1024x768 mode.

- Fix memory leaks if attach method failed
- Print EDID when -v passed to the kernel

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.

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.)

Add i.MX 6 IPU driver and enable it in IMX6 config

Add i.MX 6 IPU driver and enable it in IMX6 config

Current functionality is somewhat limited: driver assumes that there
is only one active IPU unit (IPU1) and that video output is DI0 and
video mode is 1024x768. For more advanced functionality driver requires
proper clock management which is work in progress. At the moment driver
assumes that pixel clock is configured by u-boot for 1026x768 mode.
