This patch adds macros for ns16550 port initialisation
and single char output. The macros can be used in
MIPS asm pbl code.

Ingenic JZ4755 SoC (JZ4750D family) has three UARTs.
So we can give to the user choose which one of them
to use for low level debug (debug_ll) output.
Also this commit adapts the only JZ4755 board
(Ritmix RZX50) for using the new debug_ll port
selection.

After Reset VMMC goes to default VSEL. This is not a clean power cycle for
some SD cards.
Set flag WR_S for VMMC to avoid going to default VSEL.

The I/O accessors in_bexx, out_bexx, in_lexx and out_lexx are updated
to the latest Linux version.
The patch is tested on a MPC8544 based board and solved I/O access
issues on I2C devices.

Without devicetree support we print the Kernel commandline in

when doing bootm -v -v we dumped the original tree to the console.
Make sure to print the fixed tree instead so that the fixups can
be examined.

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:

This chipselect is used on RDK Zigbee connector. Since we cannot
define additional chipselect after SPI is initialized, define this one
in main SPI initialization in PCM038 SOM.

Since the info is device specific and not driver specific, attach
the callback to the device. This makes it possible to have a info
callback for a device which does not have a driver attached.
