drivers/dht: Move hold logic from SAUL to driver
...
The DHT11/DHT21/DHT22 cannot be sampled more than once a second. Previously,
a global cache was added to the SAUL adaption of the dht driver to answer with
stored values for one second after the last read. This however had two
disadvantages:
- The global cache was shared for all DHTXX devices connected. As a result
incorrect values were delivered when reading out multiple sensors over SAUL
with less than 1 second delay in between
- A user of the low level API will had to implement the same caching strategy,
resulting in code duplication
By moving the hold logic to the driver, both limitations can be overcome.

drivers/dht: Fixed assert on uninitialized data
...
Instead of asserting that parameters are valid, dht_init() contained an assert
on uninitialized data. This commit fixes that assert

drivers/dht: Added error handling
...
Previously the DHT11/DHT21/DHT22 driver ended up in an infinite loop locking up
RIOT when a communication error occurred. This commit adds a simple timeout to
the communication in order to prevent these lock ups.

drivers: replace memset by simple assignments
...
A memset was used to clear two of the SAUL values in phydat_t::val
The change is to replace that by the following
res->val[1] = 0;
res->val[2] = 0;
which makes the code more obvious.
