pwm: img: Turn final 'else if' into 'else' in img_pwm_config
When building with -Wsometimes-uninitialized, Clang warns: drivers/pwm/pwm-img.c:126:13: error: variable 'timebase' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] The final else if functions as an else; make that explicit so that Clang understands that timebase cannot be used uninitialized.
