The IPU has a fractional pixelclock divider. When used, this produces
clock jitter which especially LVDS transceivers can't handle. Allow
to disable it via platform_data.

With the IPU the way the display is connected is completely independent
of the framebuffer pixel format. So instead of specifying a pixel width
in platform_data we have to specify how the display is connected.

Convert to static inline functions and use lower case letters for function
names. Also, include mach/debug_ll.h when an architecture provides support
for debug_ll, not only when it's actually enabled. This allows architecures
to put some UART initialization code into mach/debug_ll.h which is compiled
out when debug_ll is disabled.

gpiolib user have nothing to define in their machine
specific gpio.h, so do not include it.
The only thing they could define would be ARCH_NR_GPIOS,
but currently no architecture defines it. Should an architecure
feel the need to do it this would be a good opportunity to
get rid of this limitation.

Use MMC_CAP_ names instead of MMC_MODE_. This makes it more
clear that these are capabilities of host/card and do not refer
to the current mode. These are in line with the Linux Kernel
except for MMC_CAP_MMC_HIGHSPEED_52MHZ which could be fixed
later.

This is a port of the official PLL errata workaround from Freescale.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.
This is based on U-Boot commit:

clock_notifier_call_chain() can't be called before init time. Protecting
it with IS_ENABLED(__PBL__) is not enough. This patch splits out a new
imx53_init_lowlevel_early which can be called before init time and does
not have the call to clock_notifier_call_chain() in it.

The value for i.MX53 216MHz is actually 432MHz. Use the same value
as for i.MX51 which really corresponds to 216MHz. These are the same
PLL216 values as U-Boot uses.

The external NAND boot code currently does not handle bad blocks
correctly on 2k NAND flashes. This patch adds a barebox_update
handler for external NAND boot which embeds a Bad block table in
the flashed image. The boot code will skip bad blocks found in
this bad block table then.
