mailbox: ti-msgmgr: Allocate Rx channel resources only on request
In a much bigger system SoCs, the number of Rx channels can be
many and mostly unused based on the system of choice, and not all
Rx channels need IRQs and allocating all memory at probe will be
inefficient. Some SoCs could have total threads in the 100s and usage
would be just 1 Rx thread.
Thus, request and map the IRQs and allocate memory only when needed.
Since these channels are requested by client drivers on need, our
utilization will be optimal.
