Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.
This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305. The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.

This adds the OMAP1 PWL-based LCD backlight driver. It's been in the OMAP
tree for some time. Note that OMAP2 can do similar things with the generic
timers which have PWM outputs. Such timers are more generic than the PWL
found on OMAP1 chips, but have a different EMI profile because they aren't
driven by a pseudorandom number generator.

The current attr_fgcol_ec / attr_bgcol_ec macros do a simple shift of bits
to get the color from vc_video_erase_char. For a monochrome display
however the attribute does not contain any color, only attribute bits.
Furthermore the reverse bit is lost because it is shifted out, the
resulting color is always 0.
This can bee seen on a monochrome console either directly or by setting it
to inverse mode via "setterm -inversescreen on" . Text is written with
correct color, fb_fillrects from a bit_clear / bit_clear_margins will get
wrong colors.

Ensure that the default display parameter passed in via the
device's platform data is valid. It turns out when mach-bast.c
was updated, the default_display was set outside of the display
array bounds, causing a panic on startup.
If the default_display is bigger than num_displays, then generate
an error and refuse to initialise the driver.

cleanup sweep:
- Kill ps3fb_priv.xdr_ea and ps3fb_priv.xdr_size, use info->screen_base and
info->fix.smem_len instead.
- Kill superfluous assignments to info->fix.smem_start, info->fix.smem_len,
and info->screen_base in ps3fb_set_par(). Their values never change.
- Add sparse annotations to casts to kill address space warnings

Reorganize modedb handling:
- Reorder the video modes in ps3fb_modedb, for easier indexing using
PS3AV_MODE_* numbers,
- Introduce ps3fb_native_vmode(), to convert from native (PS3AV_MODE_*) mode
numbers to struct fb_videomode *,
- Rename and move ps3fb_default_mode() to ps3fb_vmode().

On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from
the LCD controller. It's controlled by "contrast" registers though.
This patch lets boards declare that they have that kind of backlight
control. The driver can then export this control, letting screenblank and
other operations actually take effect ... reducing the typically
substantial power drain from the backlight.
Note that it's not fully cooked
- doesn't force backlight off during system suspend
- the "power" and "blank" events may not be done right
This should be easily added in the future.
