auxdisplay: constify charlcd_ops.
charlcd_ops are not supposed to change at runtime. All functions
working with charlcd_ops provided by <misc/charlcd.h> work with
const charlcd_ops. So mark the non-const structs as const.
File size before:
text data bss dec hex filename
12750 560 362 13672 3568 drivers/auxdisplay/panel.o
File size After adding 'const':
text data bss dec hex filename
12942 368 362 13672 3568 drivers/auxdisplay/panel.o
