scripts: use #!/usr/bin/env bash shebang instead of #!/bin/bash ...

Some distributions might not have bash in /bin, but in $PATH.

Using #!/usr/bin/env bash solves this, and is consistent with how the
perl and python shebangs look like in the tree.

scripts: socfpga_get_sequencer: convert potential CRLF to LF ...

If u-boot was generated under a DOS system, the sequencer files will have CRLF
linebreaks. The indent-tool has problems with this and as a result the code
will not compile anymore.
Fix up any CRLFs prior with the dos2unix tool.

scripts: socfpga: add coccinelle magic ...

Use coccinelle to cleanup the imported u-boot code some more.
This will remove:
	- debugging macros (TCL_RPT, BFM_STAGE, ALTERA_ASSERT)
	- empty if/else/for blocks resulting from macro deletion
	- some unused functions (scc_mgr_xxx)

scripts: socfpga sequencer extraction tool ...

This script extracts the socfpga sequencer from a generated u-boot
automagically. The resulting changes of the barebox tree should be
enough to compile with the new sequencer.
