[PATCH] m68k: add global variable sdhc_per_clk for m68k

[Angelo Dureghello]

From: Angelo Durgehello <angelo at kernel-space.org>

The FSL eSDHC controller supports two reference clocks. They are
platform clock and periperhal clock. The global variable sdhc_clk
has already been used for platform clock.
ColdFire also uses eSHDC controller, as in arm and powerpc,
so adding sdhc_per_clk to arch_global_data.
