atmel: at76c50x: use DEFINE_MUTEX() for mutex lock
mutex lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). Signed-off-by: Zheng Yongjun <zhengyongjun3@huawei.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20201224132456.31341-1-zhengyongjun3@huawei.com
