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.
