The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.
This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.

boot -l crashes with CONFIG_MENU disabled because blspec_alloc returns
with blspec->menu being NULL in this case. So guard the usage of
blspec->menu accordingly.

This add barebox versions of of_clk_init for parsing and registering
clock providers from DT. Also, a macro CLK_OF_DECLARE is added, that
allows to put init callbacks into its own section that can be linked
in the binary.

Due to unwind tables being generated by recent versions of gcc by
default, the x86 Barebox link fails with:
ld: section .eh_frame loaded at [00000000000197c4,000000000001f31f]
overlaps section .barebox_initcalls loaded at [00000000000197c4,0000000000019833]
Passing -fno-unwind-tables -fno-asynchronous-unwind-tables avoids this
problem.

'barebox', but it should instead be done with the 'barebox.bin'
image. Attempting to use setupmbr on the ELF barebox image simply
fails:

No MBR signature found
