MIPS: bootm: add support for generic relocation of init ramdisks
All linux kernels after v2.6 require a page-aligned location of
an external init ramdisk. Enable CONFIG_SYS_BOOT_RAMDISK_HIGH to
support this with the generic U-Boot relocation code.

fpga: zynqpl: Clear loopback mode during device init
Some versions of the Zynq first stage boot loader enable PCAP loopback
during boot regardless of whether or not the boot image includes PL
configuration. This behavior only appears in certain boot modes (notably
QSPI boot). Attempting to configure the PL with the loopback bit set
will result in timeouts and will prevent successful configuration.
In order to avoid this problem, and to avoid dependency on the version
of the FSBL used to boot the system, ensure that the loopback enable bit
is cleared when loading the driver.

Unfortunatelly, due to a typo in the driver, instead of defining

dts/Makefile: simplify dtc invocation
The invocation of dtc is significantly more complex that it could be,
in order to work around an issue on old versions of dtc, which print
a message to stdout every time they run.
Remove this workaround, on the assumption that people have or will
upgrade to a newer version of dtc. This simplifies the build rule
significantly.
Related, split the invocation of cpp and dtc into separate commands
rather than a pipeline, so that if either fail, it is detected. This has
the nice benefit of saving off the result of the pre-processing step,
allowing it to be easily inspected.
Assuming a new enough dtc (which an earlier patch enforces), dtc will
parse #line directives in its input file, and generate correct file and
line numbers in error messages, even though cpp is unconditionally
applied to its input file.
