Subject: [PATCH] cpufreq: armada-37xx: Add missing MODULE_DEVICE_TABLE

CONFIG_ARM_ARMADA_37XX_CPUFREQ is tristate option and therefore this
cpufreq driver can be compiled as a module. This patch adds missing
MODULE_DEVICE_TABLE which generates correct modalias for automatic
loading of this cpufreq driver when is compiled as an external module.

Signed-off-by: Pali Rohár <pali@...nel.org>
Fixes: 92ce45fb875d7 ("cpufreq: Add DVFS support for Armada 37xx")
