5b457e3910 regmap: Remove redundant owner field from the bus type struct
No longer used as users link directly with the bus types so the core
module infrastructure does refcounting for us.

b5ddbf465f regmap: using module facilities requires module.h
Commit b33f9cbd67 ("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.

b33f9cbd67 regmap: Specify a module license
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.

790923e56b regmap: Remove unused type and list fields from bus interface
We no longer enumerate the bus types, we rely on the driver telling us
this on init.
