This adds a sensor driver for the hyt271, hyt221, and hyt939 sensor module from
vendor iST (Innovative Sensor Technology). This sensor type is connected via i2c
bus and allows the measurement of relative humidity and temperature.
Each driver instance supports two different character device for each type
(/dev/sensor/tempX and /dev/sensor/humiX).
This driver also supports changing the i2c address of one connected sensor on
the bus. This requires a callback to the platform-specific board logic which
must ensure a power-on reset.
Optional the driver allows setting up a read interval for fetching sensor data.
This is done by a worker thread and can be useful when watching several sensors
via poll() by the userspace application.

This change makes it so that the timeout is set as part of the SDIO_WAITENABLE call instead of the SDIO_EVENTWAIT call. By doing so, you eliminate all opportunity for a race condition.

Previous fix to RNDIS response queueing caused unaligned access
to response buffer in some configurations. On ARM Cortex-M, this
would cause hardfault if optimizer used strd instruction.
Fix by allocating the buffer as uint32_t. RNDIS messages are always
a multiple of 4 bytes in size, so this ensures alignment.
Gracefully handle output queue full conditions. This shouldn't happen
in practice as the host is supposed to limit the number of commands
simultaneously in execution.
Reset the response queue on RNDIS_RESET_MSG. This way communication
can recover even if host and device get out of sync.
Sometimes Windows would send RNDIS_KEEPALIVE_MSG and RNDIS_QUERY_MSG close
to each other. This would cause the latter command to overwrite the reply for
the prior command. This in turn will cause Windows to drop the connection after
a 20 second timeout.
Easy way to reproduce the issue is to open the Windows "Adapter Status" dialog that
shows the realtime TX/RX byte counts. This causes multiple RNDIS_QUERY_MSGs per
second, and the connection will drop in less than an hour.
This commit fixes this issue, and other potential race conditions (such as USB
descriptor read in middle on RNDIS query) by using a separate queue for the reply
packets.
