Remove wrong fifo size definition for some AT91 products.
Due to a misunderstanding of some AT91 datasheets, a fifo size of 2048
(words) has been introduced by mistake. In fact, all products (AT91/AT32)
are sharing the same fifo size of 512 words.

This patch fixes the LCDC driver to avoid calling the
function sh_mobile_lcdc_start_stop(priv, 0) unless the
same function has been called before to start the LCDC
hardware.
Triggered when sh_mobile_lcdcfb.c failed to probe() due to
missing MSTP clocks.

The second argument of the probe method points to the amba_id
structure, so it's better passed with the correct type. None of the
current in-tree drivers uses the pointer, so they have only been
checked for a clean compile.
Change suggested by Russell King.

The following symbols are needlessly defined global:
default_mode
default_var
gbe_mem_phys
gbe_turn_off
gbefb_exit
gbefb_init
gbefb_setup
This error was noticed by namespacecheck when compiling ip32_defconfig.
This patch makes the symbols static.

The required I2C modules are now selected automatically by the means
of select statements in Kconfig, so there is no point in confusing the
users with options he/she would be supposed to enable manually.

The software fillrect routines do not work properly when the number of
pixels per machine word is not an integer. To see that, run the following
command on a fbdev console with a 24bpp video mode, using a
non-accelerated driver such as (u)vesafb:
reset ; echo -e '\e[41mtest\e[K'
The expected result is 'test' displayed on a line with red background.
Instead of that, 'test' has a red background, but the rest of the line
(rendered using fillrect()) contains a distored colorful pattern.
This patch fixes the problem by correctly computing rotation shifts. It
has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

Uwe Geuder noted that he gets random bitmaps on a text console if he tried
to type extended characters (like the e acute). For him everything above
unicode 0xa0 was corrupted.
After some digging there seems to be a little culprit in vgacon since the
beginning of ages (well git). The function vgacon_font_get will store the
number of characters correctly in font->charcount but then calls to
vgacon_do_font_op(..., 0, 0). Which means only the lower 256 characters
are actually stored to the fontdata. The rest is left untouched. So the
next time that saved data is used, the garbled font appears. This happens
on every switch between text consoles.

uvesafb incorrectly sets the length of the color fields to 6 bits for
PSEUDOCOLOR modes, even though 8 bits are always used per pixel. Fix this
by setting the length to 8.
The switch of the DAC width from the default 6 bits to 8 bits is retained
and tracked internally in the driver, but never exposed to userspace.
