To start synchronizing OF API of barebox with linux OF API, this adds
a length pointer to of_find_property. Also all current users of that
function are updated to reflect the API change.

Barebox compares compatible, node names, and property names with strcmp.
Linux by default compares compatible and node names with strcasecmp. To
avoid inconsitencies between Barebox and Linux dts files, we convert to
these default string compare functions.

Current implementation of of_property_write_u32 does free old property
values and allocates new values depending on the size passed. While
copying the new values to the property, corresponding length is not
set. This makes of_property_write_u32 set the length of the new property
values and also adds a API header describing the function.

of_match_node checks for compatiblity between a set of matches and a
node. Neither the matches nor node pointer are checked for validity.
This adds the required checks to of_match_node.

Some boards need some more tries to successfully detect a phy. This
happens for example on the pcm038. Try up to four times to detect a
phy.

In omap4_enable_all_clocks we not only enable the mcbsp clocks, but also
change the source from ABE_24M_FCLK to 24M_FCLK. Revert this and default
to the reset state.

This patch fixes boot_mode detection for non-internal boot and
bootsource detection for i2c boot. Further, the bootsouce_instance
is now determined for spi, i2c, and mmc/sd boot.

By default CONFIG_JZ4750D_DEBUG_LL_UART0 is selected.
This can confuse the Ritmix RZX50 user as the board
has only UART1 connected.

This commit moves the C debug_ll code from
the MIPS <debug_ll_ns16550.h> header file to
the MIPS <asm/debug_ll_ns16550.h> header file,
so the C code and the asm code can use the same
register address macros.

Set DEBUG_LL_UART_DIVISOR to use <asm/debug_ll_ns16550.h>.
The JZ4755 uses 24 MHz as the main reference frequency (EXCLK).
The UART controller can work on full EXCLK or on EXCLK/2.
Just now we use EXCLK/2 legacy clock setup made by U-Boot.
So set UART controller base frequency to 12 MHz.

The NT disk Signature is a unique 32-bit value in the MBR allowing
to identify a MSDOS partitioned disk. The signature can be used to
specify the Linux rootfs.
This patch adds support for the NT disk Signature in the form of a
device parameter which can both be read and written.

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.
