When building a kernel with support for both ARMv6 and ARMv7 but
no MMU, the call from tauros2_internal_init to adjust_cr causes
a link error. While that could probably be resolved, we don't
actually support cache-tauros2 on ARMv6 any more. All PJ4 CPU
implementations support both ARMv6 and ARMv7 and we already assume
that we are using them only in ARMv7 mode.

Removing the ARMv6 code path reduces the code size and avoids
the linker error.

CONFIG_NEON is meant to be user-selectable. Turning it on
unconditionally means we can't build a smaller kernel when
we don't need it, and causes build errors if CONFIG_VFP
is not also enabled.

To still have neon enabled however, we need to turn it on
now in multi_v7_defconfig and mvebu_v7_defconfig.

Without this patch I am getting a unhandled fault exception like this

Unhandled fault: imprecise external abort (0x1c06) at 0xb6f89005
Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000007

The address which is here 0xb6f89005 changes from boot to boot, with a
new build the changes are bigger. With kernel 3.10 I have also seen
this fault at different places in the boot process, but starting with
3.11 they are always occurring after the "Freeing unused kernel memory"
message. I never was able to completely boot to userspace without this
handler. The abort code is constant 0x1c06. This fault just happens
once in the boot process I have never seen it happing twice or more.

I also tried changing the CPSR.A bit to 0 in init_early, with this code
like Afzal suggested, but that did not change anything:
asm volatile("mrs r12, cpsr\n"
	"bic r12, r12, #0x00000100\n"
	"msr cpsr_c, r12" ::: "r12", "cc", "memory");

Disabling the L2 cache by building with CONFIG_CACHE_L2X0 unset did not
help.

This workaround was copied from the vendor code including most of the
comments. It says it they think this is caused by the CFE boot loader
used on this device. I do not have any access to any datasheet or
errata document to check this.
