Subject: [PATCH] pwm: atmel: remove redundant initialization of variable timeout

The variable timeout is being initialized with a value that is never
read, it is being re-assigned the same value later on. Remove the
redundant initialization and keep the latter assignment because it's
closer to the use of the variable.
