ACPI_VIDEO keeps causing problems with circular Kconfig dependencies,
as it depends on a couple of other symbols, and it gets selected by
drivers that may end up being depending on others.
This is an attempt to simplify this by changing all drivers that
currently 'select ACPI_VIDEO' to use 'depends on'. This by itself
simplifies the dependency lists for the other drivers. We make
ACPI_VIDEO 'default y' to avoid having it turned off for 'make
oldconfig' users. This should again be fine as x86 users will
normally want this enabled and the option is not available elsewhere.
I'm moving the 'select BACKLIGHT_CLASS_DEVICE/BACKLIGHT_LCD_SUPPORT'
into ACPI_VIDEO as a further simplification, those were already
selected by anything that selected ACPI_VIDEO before.
Changing the INPUT dependency in ACPI_CMPC is necessary to avoid a
circular dependency with X86_PLATFORM_DEVICES/NOUVEAU.
