[PATCH] mailbox: qcom-ipcc: Support multiple channels for a given client

[Huang Yiwei]

Recently a new use case where two signals for the same protocol and
client is needed, that means there will be more than one channel
for a mbox node. Current driver only supports one channel, so need
to remove the limitation and let the driver find every channel
correctly.
