Add a sub-driver for SDIO based chipsets which implements the following functionality: - register accessors for 8, 16 and 32 bits for all states of the card (including usage of 4x 8 bit access for one 32 bit buffer if the card is not fully powered on yet - or if it's fully powered on then 1x 32 bit access is used) - checking whether there's space in the TX FIFO queue to transmit data - transfers from the host to the device for actual network traffic, reserved pages (for firmware download) and H2C (host-to-card) transfers - receiving data from the device - deep power saving state The transmit path is optimized so DMA-capable SDIO host controllers can directly use the buffers provided because the buffer's physical addresses are 8 byte aligned. The receive path is prepared to support RX aggregation where the chipset combines multiple MAC frames into one bigger buffer to reduce SDIO transfer overhead.
