The reset control API has two modes: exclusive access, where the driver
expects to have full and immediate control over the state of the reset
line, and shared (clock-like) access, where drivers only request reset
deassertion while active, but don't care about the state of the reset line
while inactive.

Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior.

This series converts all drivers that currently implicitly request
exclusive reset controls to the corresponding explicit API call. It is,
for the most part, generated from the following semantic patch:

expression rstc, dev, id;
@@
-rstc = reset_control_get(dev, id);
+rstc = reset_control_get_exclusive(dev, id);

After all driver patches are applied, the temporary transition helpers
can be removed.
