HID: hid-picolcd depends on LCD_CLASS_DEVICE
HID_PICOLCD should depend on LCD_CLASS_DEVICE, otherwise the
build fails when HID_PICOLCD=y and LCD_CLASS_DEVICE=m:
hid-picolcd.c:(.text+0x84523f): undefined reference to `lcd_device_unregister'
hid-picolcd.c:(.text+0x8478ab): undefined reference to `lcd_device_register'
hid-picolcd.c:(.text+0x84c15f): undefined reference to `lcd_device_unregister'
Same applies to FB, BACKLIGHT_CLASS_DEVICE and LEDS_CLASS.
Add suboptions for those features to handle the deps on kbuild side
and just check HID_PICOLCD_* in the code.
