By default, the system firmware enables the mpm wakeup functionality
of all the supported GPIOs. However, certain usecases demand that
this capability be disabled on certain gpios. Hence, provide a
generic interface to disable the GPIOs as needed.

Since PCIe remap window register access and actual PCIe device
register access may go through different NoCs, read it back after
writing to remap window register to make sure it has taken effect.
This is able to avoid NOC errors when accessing the actual device
register which the remap window value applies to.

If CONFIG_QCOM_COMMAND_DB=n the following compilation errors will be
seen. Fix this by including the appropriate linux headers.
./include/soc/qcom/cmd-db.h: In function ‘cmd_db_read_aux_data’:
./include/soc/qcom/cmd-db.h: error: implicit declaration of function ‘ERR_PTR’;

Fix data race in prepend_path() with re-reading mnt->mnt_ns twice
without holding the lock.
is_mounted() does check for NULL, but is_anon_ns(mnt->mnt_ns) might
re-read the pointer again which could be NULL already, if in between
reads one of kern_unmount()/kern_unmount_array()/umount_tree() sets
mnt->mnt_ns to NULL.
This is seen in production with the following stack trace:

For synchronous messages sent from the agent to platform,
agent waits for response for 30 milli seconds (max_rx_timeout)
before timing out if response gets delayed from platform.
Increase the timeout value to 1 second to minimize message
send failures in case of delays.
