[PATCH] Add build information to the beginning of the binary

[Eugene Krasnikov]

With this commit both htc_9271.fw and htc_7010.fw will have build
information in the beginning of the file. Driver can read this
information even before loading fw to the chip.

Build information format:
	u32	major;
	u32	minor;
	u32	tag;
	char	commit_id[40];
	char	user_name[32];
