[U-Boot] [PATCH 0/1] fix ARM DCC support for ARMv7 based cores (e.g. CortexA)

arm_dcc.c supported ARMv4 (ARM7) to ARMv6 (ARM11) correctly. All recent
CortexA/ARMv7 based cores share the mrc/mcr coprocessor calls of ARMv6.
Due to the missing #ifdef the ARM7/ARMv4 calls are used as soon as
CONFIG_CPU_V7 is defined. This results in an undefined instruction exception.
