Let's use the i.MX common miscellaneous reset API
to reset the LCDIF block so that we may eliminate
a random hang issue at the arch_preboot_os() stage
when we disable the LCDIF. This patch also waits
for a VSYNC interrupt to guarantee the reset is
done at the VSYNC edge, which somehow makes the
LCDIF consume the display FIFO(?) and helps the
LCDIF work normally at the kernel stage.

Add a new interface "mxs_lcd_panel_setup" to setup fb parameters and
specifies the LCDIF controller for multiple controllers of iMX6SX.
Pass fb parameters via "videomode" env remains work if the new interface
is not called before video initialization.
Modify LCDIF clock interface "mxs_set_lcdclk" to support multiple
LCDIF controllers on iMX6SX.

The LCDIF interface doesn't give us any means to do continuous refresh
when driving a SmartLCD. To work this around, we produce a special
circular DMA descriptor, which only writes the HW_LCDIF_CTRL0 register
and sets the RUN bit.

Add hook that allow configuring SmartLCD attached the MXS LCDIF
controller operating in System-Mode. This hook can be overriden
by a platform-specific SmartLCD programming routine, which writes
the SmartLCD specific values into it's registers.
Also, this patch makes sure the SYNC signals are off for the
SmartLCD case.

Allocate the framebuffer aligned so it can be flushed
and the flush_dcache_range() function won't complain.

BOOT: SSP SD/MMC #0, 3V3
DRAM: 128 MiB
MMC: MXS MMC: 0
Video: MXSFB: 'videomode' variable not set!In: serial
Break the line of the warning message in order to have a better reading format.

Currently the mxsfb driver takes the display timings from the 'videomode'
environment variable.
Provide an example on how to set 'videomode' for using splash screen on
mx23evk and mx28vk boards.
