drivers: base: handle module_kobject creation

[ Upstream commit f95bbfe18512c5c018720468959edac056a17196 ]

module_add_driver() relies on module_kset list for
/sys/module/<built-in-module>/drivers directory creation.

Since,
commit 96a1a2412acba ("kernel/params.c: defer most of param_sysfs_init() to late_initcall time")
drivers which are initialized from subsys_initcall() or any other
higher precedence initcall couldn't find the related kobject entry
in the module_kset list because module_kset is not fully populated
by the time module_add_driver() refers it. As a consequence,
module_add_driver() returns early without calling make_driver_name().
Therefore, /sys/module/<built-in-module>/drivers is never created.

Fix this issue by letting module_add_driver() handle module_kobject
creation itself.
