msm: mhi-dev: Send channel state broadcasts for QRTR channels 



Set the channel attribute for QRTR channels (MHI_CLIENT_IPCR_OUT
and MHI_CLIENT_IPCR_IN) so that QRTR client gets the uevent
broadcast when the channel state changes. Change the naming
for the structure to mhi_chan_attr_table since kernel clients are
also configured using the same structure.
