s5p-fimc: Keep local copy of sensors platform data

Use a copy of sensor platform data structure, rather than referencing
external platform data from the driver. This allows to fill the local
copy with values parsed from device tree when needed.

ARM: samsung: move platform_data definitions

Platform data for device drivers should be defined in
include/linux/platform_data/*.h, not in the architecture
and platform specific directories.

This moves such data out of the samsung include directories

ARM: Samsung: Remove unused fields from FIMC and CSIS platform data

The MIPI-CSI2 bus data alignment is now being derived from the media
bus pixel code, the drivers don't use the corresponding structure
fields, so remove them. Also remove the s5p_csis_phy_enable callback
which is now used directly by s5p-csis driver.

ARM: Samsung: Change __s5p_mipi_phy_control() function signature

Replace pdev argument __s5p_mipi_phy_control() helper with plain int
so MIPI-CSIS hardware instance index can be passed directly making
the function usable on platforms instatiated from device tree.

s5p-csis: Replace phy_enable platform data callback with direct call

The phy_enable callback is common for all Samsung SoC platforms,
replace it with direct function call so the MIPI-CSI2 DPHY control
is also possible on device tree instantiated platforms.

s5p-fimc: Remove unused platform data structure fields

alignment, fixed_phy_vdd and phy_enable fields are now unused
so removed them. The data alignment is now derived directly
from media bus pixel code, phy_enable callback has been replaced
with direct function call and fixed_phy_vdd was dropped in commit

s5p-csis: Allow to specify pixel clock's source through platform data

Depending on the sensor configuration it might be required to adjust
the CSIS's output pixel clock so it is greater than its input pixel
clock, in order to avoid the input data FIFO overflow.

Use platform data to select SCLK_CSIS clock from CMU as a source, rather
than CSI APB clock.
