[PATCH] staging/panel: Mark local functions as static (fix smatch warnings)

[Peter Huewe <peterhuewe@gmx.de>]

smatch complains about the following functions:
panel.c:188:1: warning: symbol 'logical_inputs' was not declared. Should it be static?
panel.c:569:6: warning: symbol 'old_keypad_profile' was not declared. Should it be static?
panel.c:580:6: warning: symbol 'new_keypad_profile' was not declared. Should it be static?
panel.c:593:6: warning: symbol 'nexcom_keypad_profile' was not declared. Should it be static?
panel.c:672:6: warning: symbol 'pin_to_bits' was not declared. Should it be static?
panel.c:1375:6: warning: symbol 'panel_lcd_print' was not declared. Should it be static?
panel.c:1382:6: warning: symbol 'lcd_init' was not declared. Should it be static?
panel.c:2181:5: warning: symbol 'panel_init' was not declared. Should it be static?

Add the static keyword to silence these warnings and make smatch happy.
