video: fbdev: s3fb: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
20994 2440 8 23442 5b92 drivers/video/fbdev/s3fb.o

File size after adding 'const':
text data bss dec hex filename
21506 1928 8 23442 5b92 drivers/video/fbdev/s3fb.o
