[PATCH] ARM: S5PV310: Add SMDKC210 board support file

[Kukjin Kim]

This patch adds Samsung SMDKC210 board support file. The SoC
of SMDKC210, S5PC210(MCP) is one of package option of S5PV310.
And because composition of SMDKC210 and SMDKV310 differs, need
SMDKC210 with SMDKV310.

NOTE:
This is for next merge window not this, because I don't want to apply
new patch which was submitted in merge window as per Russell's suggestion.
But this can help to developers and customers who want to use SMDKC210.
And this can be used base code for SMDKC210 development in 2.6.36-rcX.
