[PATCH] tags: add a space regex to DECLARE_BITMAP

[Zhaoyu Liu <zackary.liu.pro@gmail.com>]

When "make tags", it prompts a warning:

    ctags: Warning: drivers/pci/controller/pcie-apple.c:150:
    null expansion of name pattern "\1"

The reason is that there is an indentation beside arguments of
DECLARE_BITMAP, but it can parsed normally by gtags. It's also
allowed in C.

So fix this regex temporarily, and wait for better solutions
applied to other regexs.
