Save error handling and unwinding code in drivers by providing managed
versions of the regmap init functions, simplifying usage.

No longer used as users link directly with the bus types so the core
module infrastructure does refcounting for us.

Commit b33f9cbd ("regmap: Specify a module license") added a
MODULES_LICENSE to this file without adding an include of module.h.

module.h should have been included anyway, since this file has
EXPORT_SYMBOLs as well.  With the pending module.h split up, this would
probably have caused build problems.

CONFIG_REGMAP_I2C/SPI are set to m when selected by a tristate config
option that's set to m. The regmap modules don't specify a license, so
fail to link to regmap_init at load time, since that is EXPORT_SYMBOL_GPL.
Fix this by specifying a license for the regmap modules.

We no longer enumerate the bus types, we rely on the driver telling us
this on init.
