crypto: atmel - Avoid flush_scheduled_work() usage

Browse Source 
Flushing system-wide workqueues is dangerous and will be forbidden.
Replace system_wq with local atmel_wq.

If CONFIG_CRYPTO_DEV_ATMEL_{I2C,ECC,SHA204A}=y, the ordering in Makefile
guarantees that module_init() for atmel-i2c runs before module_init()
for atmel-ecc and atmel-sha204a runs.
