We already have the DEFINE_SHOW_ATTRIBUTE,There is no need to define such
a macro,so remove define_genpd_open_function and define_genpd_debugfs_fops.
Also use DEFINE_SHOW_ATTRIBUTE to simplify somecode.

It would be good at least to split the genpd changes off into a separate patch.
The regmap and comonent changes appear to be independent of each other
too, so I would put them into separate patches either for easier
handling.
