target/cortex_a: fix compile error for uninitialized variable 

Commit ad6c71e151 introduced the
variable "mmu_enabled" whose pointer is passed to cortex_a_mmu()
that initialises it.
This initialization is not visible to the compiler that issue
a compile error.
The same situation is common across the same file and the usual
workaround is to initialize it to zero; thus the same fix i
applied here.
