platform/x86: panasonic-laptop: Remove redundant checks from 3 functions

Browse source

The device pointer cannot be NULL in acpi_pcc_hotkey_add() and
acpi_pcc_hotkey_remove() because these functions are ACPI driver
callbacks and NULL is never passed to any of them as an argument.

Likewise, acpi_pcc_hotkey_resume() is a resume callback of a
device driver and NULL is never passed to it as an argument, so
the dev pointer in it cannot be NULL.

Moreover, since acpi_pcc_hotkey_remove() and acpi_pcc_hotkey_resume()
can only run after acpi_pcc_hotkey_add() has completed successfully,
the acpi_driver_data() of the device object used by them cannot be
NULL when they run.

Drop all of the redundant NULL checks of the pointers mentioned above.
