qcacmn: Support REO2SW ring pointer update threshold configuration

Support REO2SW ring pointer update threshold configuration,
it is helpful for PCIe utilization improvement.
timer based threshold - M: issue pointer updates when M micro
seconds has elapsed.
number based threshold - N: issue pointer updates when N entries
updates occur.
