qcom: rpm-smd: Increase wait timeout during sleep set 



RPM driver waits for 5 us when the the tx buffer is full and eventually
times out after 250us. This isn't sufficient time for RPM to consume the
data. This could result in a unsuccessful attempts to send sleep set
buffers.

Increase the timeout to 100us to give RPM sufficient time to read through
the data.
