the Advanced Security SD (ASSD) protocol

and the M-Commerce Extension Specification 1.10
are supported in Linux.
Welcome advice and comments.

This patch reworks the wake-up support in the sdhci driver.
It is now able to wake-up the system on: Card interrupts,
Card insertion and Card removal events.
This has been tested on ST STB where can make sense to
wake-up the box as soon as a card is inserted.
