The auxdisplay Kconfig is confusing. It creates two separate menus even though the settings are closely related. Moreover, the options for setting the boot message depend on CONFIG_PARPORT even though they are used by drivers that do not.
Clear up the confustion by moving the "Parallel port LCD/Keypad" menu under auxdisplay where it logically belongs. Change the boot message options to depend only on CONFIG_CHARLCD, making them accessible also when only the HD44780 is selected. Since the "Parallel port LCD/Keypad" driver now has a new dependency on CONFIG_AUXDISPLAY, rename its Kconfig symbol and keep the old one such that make oldconfig will not disable the driver.
