irqchip: IMX_MU_MSI should depend on ARCH_MXC

The Freescale/NXP i.MX Messaging Unit is only present on Freescale/NXP
i.MX SoCs.  Hence add a dependency on ARCH_MXC, to prevent asking the
user about this driver when configuring a kernel without Freescale/NXP
i.MX SoC family support.

While at it, expand "MU" to "Messaging Unit" in the help text.
