cpufreq: imx6q: fix possible object reference leak
The call to of_node_get returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./drivers/cpufreq/imx6q-cpufreq.c:391:4-10: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 348, but without a corresponding object release within this function. ./drivers/cpufreq/imx6q-cpufreq.c:395:3-9: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 348, but without a corresponding object release within this function.
