crypto: qat - fix firmware loading failure for GEN6 devices
QAT GEN6 hardware requires a minimum 3 us delay during the acceleration
engine reset sequence to ensure the hardware fully settles.
Without this delay, the firmware load may fail intermittently.
Add a delay after placing the AE into reset and before clearing the reset,
matching the hardware requirements and ensuring stable firmware loading.
Earlier generations remain unaffected.
