Add a simple LCD driver which uses SDL to display the image. We update the
image regularly, while still providing for reasonable performance.
Adjust the common lcd code to support sandbox.
For command-line runs we do not want the LCD to be displayed, so add a
--show_lcd option to enable it.

.bmp files contain 32-bit integers aligned at offsets of +2, +6,
et cetera within the bmp_header structure (see include/bmp_layout.h).
Support for gzip-compressed .bmp files is present in the cfb_console
display subsystem by uncompressing them prior to use.
This patch forces the in-memory header to be aligned properly
for these compressed images by extracting them to a 2-byte
offset in the memory returned by malloc. Since malloc will always
return a 4-byte aligned value, this forces the .bmp header
fields to be naturally aligned on 4-byte addresses.
Refer to these files for more details:

Depending on the firmware's video options [1] the active SDTV or
HDTV mode can yield a framebuffer with noncontiguous horizontal lines,
giving a messed up display, for both, u-boot and the loaded kernel.
Fix this by setting lcd_line_length to the pitch value of the configured
framebuffer.

Currently the HDMI splash screen image quality on mx6solo does not show a
very stable image.
By comparing the IPU driver from U-boot with the one from FSL 4.1.0 BSP,
we can see that there is an inverted logic for setting the DI_GEN_POL_CLK bit.
>From FSL BSP [1] we have:
if (!sig.clk_pol)
di_gen |= DI_GEN_POLARITY_DISP_CLK;
Applying the same logic into U-boot fixes the HDMI image stability.
