Rework lcd_enabled and lcd_set/call_enable hook

Browse source 
a) lcd_enabled() is now lcd_active(), and is available for HAVE_LCD_SLEEP only targets (e.g. ipod video) too. It was depandent on HAVE_LCD_ENALE only before
b) rename the hook accordingly, and implement the hook for other other targets too (e.g. the clip [the only mono target with lcd_enable/lcd_sleep yet, so the code is still in the lcd driver], ipod, fuze, c200)
