Subject: [PATCH mmotm] hid-picolcd: depends on LCD_CLASS_DEVICE

From: Randy Dunlap <randy.dunlap@...cle.com>

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'
