platform/x86: panasonic-laptop: remove sparse_keymap_free() calls
As sparse_keymap_setup() now uses a managed memory allocation for the keymap copy it creates, the latter is freed automatically. Remove all calls to sparse_keymap_free(). As this reduces acpi_pcc_destroy_input() to one line, replace all calls to that function with direct calls to input_unregister_device().
