====================
net: ipa: GSI interrupt updates

This series implements some updates for the GSI interrupt code,
buliding on some bug fixes implemented last month.

The first two are simple changes made to improve readability and
consistency.  The third replaces all msleep() calls with comparable
usleep_range() calls.

The remainder make some more substantive changes to make the code
align with recommendations from Qualcomm.  The fourth implements a
much shorter timeout for completion GSI commands, and the fifth
implements a longer delay between retries of the STOP channel
command.  Finally, the last implements retries for stopping TX
channels (in addition to RX channels).
