[U-Boot] [PATCH v3 1/2] mxc: Define architecture identifier

[Benoît Thébaudeau]

Define ARCH_MXC for i.MX devices. This is useful to identify features or
behaviors common to all i.MX SoCs.

The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

Changes for v2: None.
Changes for v3:
 - Rename ARCH_IMX to ARCH_MXC to emphasize the difference between mxc and mxs.
