[U-Boot] [PATCH v1] x86: acpi: Adopt new version of iASL compiler

[Andy Shevchenko]

The commit

  f9a88a4c1cd0 ("iASL: Enhance the -tc option (create AML hex file in C)")

in ACPICA project changed a template of the a of variable that is used
in the generated C-file. Now, instead of hard coded "AmlCode" the
"%s_aml_code" is in use, where the prefix is a lowered case base name of
the output file. In our case it will be "dsdt" producing a name as
"dsdt_aml_code".

The quick solution is to call sed which replaces new name by the old one
to keep compatibility with old version of iASL.

The long term solution would be to modify code to use the new name
because it more scalable.
