[PATCH] scsi: aic7xxx: fix firmware build fatal error

[Wang Jinchao]

When building with CONFIG_AIC7XXX_BUILD_FIRMWARE=y, two fatal errors
are reported as shown below:
> aicasm_gram.tab.c:203:10: fatal error: aicasm_gram.tab.h:
> No such file or directory
> aicasm_macro_gram.tab.c:167:10: fatal error: aicasm_macro_gram.tab.h:
> No such file or directory
Fix these issues to make randconfig builds more reliable.
