Add timer based auto deep sleep feature in libertas driver which can be configured using iwconfig command. This is tested on SD8688, SD8686 cards with firmware versions 10.38.1.p25, 9.70.4.p0 respectively on 32-bit and 64-bit platforms. Tests have been done for USB/CS cards to make sure that the patch won't break USB/CS code. We didn't test the if_spi driver.
