kconfig: Fix streamline_config to read multi line deps in Kconfig files
I noticed that some Kconfig files have multi line dependencies that continue with a backslash. Those dependencies on the next line will be missed by streamline_config. For example: config CS89x0 tristate "CS89x0 support" depends on NET_ETHERNET && (ISA || EISA || MACH_IXDP2351 \ || ARCH_IXDP2X01 || MACH_MX31ADS) The "|| ARCH_IXDP2X01 || MACH_MX31ADS)" will not be processed. This patch adds code to handle this case. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
