Moved, renamed, and deleted files

The original directory structure was scattered and unorganized.
Changes are basically to make it look like kernel structure.

+ * was done by SMM code, which could cause unsynchronized concurrent
+ * accesses to the SMBus registers, with potentially bad effects. Thus you
+ * should be very careful when adding new entries: if SMM is accessing the
+ * Intel SMBus, this is a very good reason to leave it hidden.
+ *
+ * Likewise, many recent laptops use ACPI for thermal management. If the

+ * These chips implement the four main memory card controllers (SD, MMC, MS, xD)

+ * It happens that they implement SD and MMC

+ * and directs them to the MMC controller - so the SDHCI driver never sees
+ * them.
+ *
+ * To get around this, we must disable the useless MMC controller.
+ * At that point, the SDHCI controller will start seeing them
+ * It seems to be the case that the relevant PCI registers to deactivate the
+ * MMC controller live on PCI function 0, which might be the cardbus controller
+ * or the firewire controller, depending on the particular chip in question
+ *
+ * This has to be done early, because as soon as we disable the MMC controller
