kernel: remove obsolete kernel version switches for 4.14

This removes switches dependent on kernel version 4.14 as well as
several packages/modules selected only for that version.

This also removes sched-cake-virtual, which is not required anymore
now that we have only one variant of cake.

- *
- *  The behaviour of this driver can be altered by setting some parameters

- *  The following parameters are adjustable:
- *
- *	bus0	These four arguments can be arrays of

- *	bus3	<id>,<sda>,<scl>,<udelay>,<timeout>,<sda_od>,<scl_od>,<scl_oo>

- *  where:
- *
- *  <id>	ID to used as device_id for the corresponding bus (required)
- *  <sda>	GPIO pin ID to used for SDA (required)
- *  <scl>	GPIO pin ID to used for SCL (required)
- *  <udelay>	signal toggle delay.
- *  <timeout>	clock stretching timeout.
- *  <sda_od>	SDA is configured as open drain.
- *  <scl_od>	SCL is configured as open drain.
- *  <scl_oo>	SCL output drivers cannot be turned off.
- *
- *  See include/i2c-gpio.h for more information about the parameters.
- *
- *  If this driver is built into the kernel, you can use the following kernel

-	  This is an SPI driver to register 1 to 4 custom SPI buses using
-	  GPIO lines. Each bus can have up to 8 slaves.
-	  The devices will be exposed to userspace as /dev/spidevX.X
-	  
-	  This module is maily intended to interface microcontrollers
-	  and other SPI devices without a specific kernel driver.
-
-	  This support is also available as a module.  If so, the module
-	  will be called spi-gpio-custom.

- *
- *  The behaviour of this driver can be altered by setting some parameters
- *  from the insmod command line.
- *
- *  The following parameters are adjustable:
- *
- *	bus0	These four arguments can be arrays of
- *	bus1	1-8 unsigned integers as follows:
- *	bus2
- *	bus3	<id>,<sck>,<mosi>,<miso>,<mode1>,<maxfreq1>,<cs1>,...
- *
- *  where:
- *
- *  <id>	ID to used as device_id for the corresponding bus (required)
- *  <sck>	GPIO pin ID to be used for bus SCK (required)
- *  <mosi>	GPIO pin ID to be used for bus MOSI (required*)
- *  <miso>	GPIO pin ID to be used for bus MISO (required*)
- *  <modeX>	Mode configuration for slave X in the bus (required)
- *		(see /include/linux/spi/spi.h)
- *  <maxfreqX>	Maximum clock frequency in Hz for slave X in the bus (required)
- *  <csX>	GPIO pin ID to be used for slave X CS (required**)
- *
- *	Notes:
- *	*	If a signal is not used (for example there is no MISO) you need
- *		to set the GPIO pin ID for that signal to an invalid value.
- *	**	If you only have 1 slave in the bus with no CS, you can omit the
- *		<cs1> param or set it to an invalid GPIO id to disable it. When
- *		you have 2 or more slaves, they must all have a valid CS.
- *
- *  If this driver is built into the kernel, you can use the following kernel
- *  command line parameters, with the same values as the corresponding module
- *  parameters listed above:
- *
- *	spi-gpio-custom.bus0
- *	spi-gpio-custom.bus1
- *	spi-gpio-custom.bus2

- *
- *  The behaviour of this driver can be altered by setting some parameters
- *  from the insmod command line.
- *
- *  The following parameters are adjustable:
- *
- *	bus0	These four arguments must be arrays of
- *	bus1	3 unsigned integers as follows:
- *	bus2
- *	bus3	<id>,<pin>,<od>
- *
- *  where:
- *
- *  <id>	ID to used as device_id for the corresponding bus (required)
- *  <sda>	GPIO pin ID of data pin (required)
- *  <od>	Pin is configured as open drain.
- *
- *  See include/w1-gpio.h for more information about the parameters.
- *
- *  If this driver is built into the kernel, you can use the following kernel
- *  command line parameters, with the same values as the corresponding module
- *  parameters listed above:
- *
- *	w1-gpio-custom.bus0
- *	w1-gpio-custom.bus1
- *	w1-gpio-custom.bus2
