The atmel-isc-base is getting crowded. Split the clock functions into
atmel-isc-clk.c.

Microchip CSI2DC (CSI2 Demultiplexer Controller) is a misc bridge device
that converts a byte stream in IDI Synopsys format (coming from a CSI2HOST)
to a pixel stream that can be captured by a sensor controller.

Building VIDEO_ATMEL_ISC as module and VIDEO_ATMEL_XISC as built-in
(or viceversa) causes build errors:
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o: in function `isc_async_complete':
atmel-isc-base.c:(.text+0x40d0): undefined reference to `__this_module'
or1k-linux-ld: atmel-isc-base.c:(.text+0x40f0): undefined reference to `__this_module'
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(.rodata+0x390): undefined reference to `__this_module'
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x4): undefined reference to `__this_module'
or1k-linux-ld: drivers/media/platform/atmel/atmel-isc-base.o:(__param+0x18): undefined reference to `__this_module'
This is caused by the file atmel-isc-base.c which is common code between
the two drivers.
The solution is to create another Kconfig symbol that is automatically
selected and generates the module atmel-isc-base.ko. This module can be
loaded when both drivers are modules, or built-in when at least one of them
is built-in.

This splits the Atmel ISC driver into a common base: atmel-isc-base.c
and the driver probe/dt part , atmel-sama5d2-isc.c
This is needed to keep a common ground for the sensor controller which will
be reused.
The atmel-isc will use the common symbols inside the atmel-isc-base
Future driver will also use the same symbols and redefine different aspects,
for a different version of the ISC.
This is done to avoid complete code duplication by creating a totally
different driver for the new variant of the ISC.
