[PATCH] scripts: imx: Ignore ';' and '\n' in quotes

[Albert Schwarzkopf <a.schwarzkopf@phytec.de>]

The current behaviour treats semicolons the same as end of line.
This breaks when they are found inside quoted strings, as is the
case for PKCS#11 URIs for example.

Ignore newlines and semicolons in quotes when parsing commands.
