[PATCH] ARM: imx: allow support to be disabled

[swarren@wwwdotorg.org (Stephen Warren)]

From: Stephen Warren <swarren@nvidia.com>

Since ARCH_MXC's Kconfig option has no string name, the user is never
presented with an option to enable/disable this setting. Rather, it is
automatically enabled based on the conditions in the def_bool entry.

Add a string, so that the user gets to choose whether to enable ARCH_MXC,
and rename the i.MX options menu so that it doesn't clash. Also, change
from "def_bool y" to "bool" to be more consistent with other machines.

Signed-off-by: Stephen Warren <swarren@nvidia.com>

Note that if Tegra and i.MX support are enabled at the same time, then
the build will fail since both Tegra's and i.MX's head.S define symbol
v7_invalidate_l1. shmobile appears to have the same conflict. Note that
patches to port Tegra to ARCH_MULTI aren't yet in linux-next, but I can
point anyone who's interested at my github tree.
