Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

+Description
+-----------
+
+This is the driver for the SMB Host controller on Acer Labs Inc. (ALI)
+M1535 South Bridge.
+
+The M1535 is a South bridge for portable systems. It is very similar to the
+M15x3 South bridges also produced by Acer Labs Inc. Some of the registers
+within the part have moved and some have been redefined slightly.
+Additionally, the sequencing of the SMBus transactions has been modified to
+be more consistent with the sequencing recommended by the manufacturer and
+observed through testing. These changes are reflected in this driver and
+can be identified by comparing this driver to the i2c-ali15x3 driver. For
+an overview of these chips see http://www.acerlabs.com
+
+The SMB controller is part of the M7101 device, which is an ACPI-compliant
+Power Management Unit (PMU).
+
+The whole M7101 device has to be enabled for the SMB to work. You can't
+just enable the SMB alone. The SMB and the ACPI have separate I/O spaces.
+We make sure that the SMB is enabled. We leave the ACPI alone.
+
+
+Features
+--------
+
+This driver controls the SMB Host only. This driver does not use
+interrupts.
