[RFC][PATCH] uncompress: use correct cache configuration for ARM11[57]6 and 11MP

[Marc Zyngier]

In arch/arm/boot/compressed/head.S, the entry for ARMv6 configuration
matches ARM1136 (0x7b). This does not work very nicely with other
ARM11 cores (1156, 1176 and 11MP) which have 0xf in the Architectural
format description, and end up matching the ARMv7 entry.

This patch adds the required entry for these SoCs.

Tested on s3c6410 and s5p6440 (both ARM1176).
