soc/samsung/exynos5420: Refactor fimd vidtcon access
Accessing the higher vidtcon variables using pointer arithmetic from the
lower address FIMD_CTRL struct is undefined behaviour, since pointers
manipulations are not allowed outside the objects they point to. The
standard-blessed way is to perform the arithmetic using integer
addresses first, and then convert that to a pointer. The end result is
the same, but avoids the risk of unsafe optimizations from an
over-zealous compiler.
