platform/x86/amd: hfi: Remove redundant assignment to .owner

The coccicheck tool reports the following warning for this driver:

./hfi.c:509:3-8: No need to set .owner here. The core will do it.

The manual assignment of .owner = THIS_MODULE; in the platform_driver
struct is redundant. The platform_driver_register() function, which is
called to register the driver, is a macro that automatically sets the
driver's owner to THIS_MODULE.

The driver core handles this assignment internally, making the explicit
initialization in the struct definition unnecessary. Remove the
unnecessary line.
