The conversion to modules requires a correct handling of the module
refcount in order to prevent to unload it if it is in use. That is
especially true with the clockevents where there is no function to
unregister them.
The core time framework correctly handles the module refcount with the
different clocksource and clockevents if the module owner is set.
Add the module owner to make sure the core framework will prevent
stupid things happening when the driver will be converted into a
module.

Recently all usages of setup_irq() was replaced by request_irq().
request_irq() does a few sanity checks that were not done in
setup_irq(), if they fail irq registration will fail. One of the check
is to ensure that non-NULL dev_id is passed in the case of shared irq.
Fix it by passing non-NULL dev_id while registering the shared irq.
Fixes: cc2550b421 ("clocksource: Replace setup_irq() by request_irq()")

request_irq() is preferred over setup_irq(). The early boot setup_irq()
invocations happen either via 'init_IRQ()' or 'time_init()', while
memory allocators are ready by 'mm_init()'.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().
Seldom remove_irq() usage has been observed coupled with setup_irq(),
wherever that has been found, it too has been replaced by free_irq().
A build error that was reported by kbuild test robot <lkp@intel.com>
in the previous version of the patch also has been fixed.
