[PATCH Resend 1/3] ARM: EXYNOS: Consolidate Kconfig entries

[Sachin Kamat <sachin.kamat@linaro.org>]

Instead of repeating the Kconfig entries for every SoC, move them under
ARCH_EXYNOS4 and 5 and move the entries common to both 4 and 5 under
ARCH_EXYNOS. Also, since the individual SoCs do not have any specific
machine/platform code, keep them as boolean symbols instead of user
selectable and select them from Exynos4 and 5 config symbols. Individual
SoC symbols can be removed eventually once the driver Kconfig dependencies
on these symbols are removed.

This is a resend of the series rebased on top of latest linux-next and
Tomasz Figa's PM consolidation series 1 and 2.
