"unsigned long" is a lousy data type when it comes to match peripheral
hardware registers with a fixed size.
Just do the obvious and match a 32-bit display format with an "u32"
data type for casting.
This fixes the logo display on 64-bit architectures, which produced
a black line on the right side of the logo with non-black backgrounds.

Currently the system hangs when the 'videomode' variable is not present
and a reset command is issued:
=> setenv videomode
=> saveenv
=> reset
(Board hangs)
lcdif_power_down() assumes that the LCDIF controller has been properly
configured and enabled, which may not be true.
To fix this issue check whether panel.frameAdrs has been initialized and
in case it has not been initialized, do not continue with the LCDIF
powerdown sequence.
Tested on a imx7dsabresd board.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

It makes not sense using u8 to hold a value on a 32-bit or 64-bit machine.
It can only bloat the code by forcing the compiler to mask the value.
Change it to uint.

Fixes: 135aa95 (clk: convert API to match reset/mailbox style)
This code currently always selects the second source. It only worked
because both sources are set up.
With the change to only init video devices that are present in the stdout

Compiling the 'bmp' command with DM and having one of the following macros
enabled:
CONFIG_BMP_16BPP, CONFIG_BMP_24BPP ONFIG_BMP_32BPP
generates this error:
drivers/video/video_bmp.c: In function ‘video_bmp_display’:
drivers/video/video_bmp.c:315:22: error: ‘lcd_line_length’ undeclared (first use in this function)
fb -= width * 2 + lcd_line_length;

This patch moves to using the correct variable instead and enables the
'bmp' command for DM again.

With DM VESA driver on x86 boards, plat->base/size/align are all
zeroes and starting address passed to alloc_fb() happens to be 1MB
aligned, so this routine does not trigger any issue. On QEMU with
U-Boot as coreboot payload, the starting address is within 1MB
range (eg: 0x7fb0000), thus causes failure in video_post_bind().
Actually if plat->size is zero, it makes no sense to do anything
in this routine. Add such check there.
