regmap: clean up regmap allocation
Putting zero length array at the end of struct is a common technique
to embed arbitrary length of members. There is no good reason to let
regmap_alloc_count() branch by "if (count <= 1)".
As far as I understood the code, regmap->base is an alias of
regmap->ranges[0].start, but it is not helpful but make the code
just ugly.
Rename regmap_alloc_count() to regmap_alloc() because the _count
suffix seems pointless.
