Subject: ARM: integrator: Delete the V3 PCI driver

Before adding a proper PCI driver in drivers/pci/host, clean out
the cruft by deleting the old driver from the machine.

- * The V3 PCI interface chip in Integrator provides several windows from
- * local bus memory into the PCI memory areas.   Unfortunately, there
- * are not really enough windows for our usage, therefore we reuse
- * one of the windows for access to PCI configuration space.  The
- * memory map is as follows:
- *
- * Local Bus Memory         Usage
- *
- * 40000000 - 4FFFFFFF      PCI memory.  256M non-prefetchable
- * 50000000 - 5FFFFFFF      PCI memory.  256M prefetchable
- * 60000000 - 60FFFFFF      PCI IO.  16M
- * 61000000 - 61FFFFFF      PCI Configuration. 16M
- *
- * There are three V3 windows, each described by a pair of V3 registers.
- * These are LB_BASE0/LB_MAP0, LB_BASE1/LB_MAP1 and LB_BASE2/LB_MAP2.
- * Base0 and Base1 can be used for any type of PCI memory access.   Base2
- * can be used either for PCI I/O or for I20 accesses.  By default, uHAL
- * uses this only for PCI IO space.
- *
- * Normally these spaces are mapped using the following base registers:
- *
- * Usage Local Bus Memory         Base/Map registers used
- *
- * Mem   40000000 - 4FFFFFFF      LB_BASE0/LB_MAP0
- * Mem   50000000 - 5FFFFFFF      LB_BASE1/LB_MAP1
- * IO    60000000 - 60FFFFFF      LB_BASE2/LB_MAP2
- * Cfg   61000000 - 61FFFFFF
- *
- * This means that I20 and PCI configuration space accesses will fail.
- * When PCI configuration accesses are needed (via the uHAL PCI
- * configuration space primitives) we must remap the spaces as follows:
- *
- * Usage Local Bus Memory         Base/Map registers used
- *
- * Mem   40000000 - 4FFFFFFF      LB_BASE0/LB_MAP0
- * Mem   50000000 - 5FFFFFFF      LB_BASE0/LB_MAP0
- * IO    60000000 - 60FFFFFF      LB_BASE2/LB_MAP2
- * Cfg   61000000 - 61FFFFFF      LB_BASE1/LB_MAP1
- *
- * To make this work, the code depends on overlapping windows working.
- * The V3 chip translates an address by checking its range within
- * each of the BASE/MAP pairs in turn (in ascending register number
- * order).  It will use the first matching pair.   So, for example,
- * if the same address is mapped by both LB_BASE0/LB_MAP0 and
- * LB_BASE1/LB_MAP1, the V3 will use the translation from
- * LB_BASE0/LB_MAP0.
- *
- * To allow PCI Configuration space access, the code enlarges the
- * window mapped by LB_BASE0/LB_MAP0 from 256M to 512M.  This occludes
- * the windows currently mapped by LB_BASE1/LB_MAP1 so that it can
- * be remapped for use by configuration cycles.
- *
- * At the end of the PCI Configuration space accesses,
- * LB_BASE1/LB_MAP1 is reset to map PCI Memory.  Finally the window
- * mapped by LB_BASE0/LB_MAP0 is reduced in size from 512M to 256M to
- * reveal the now restored LB_BASE1/LB_MAP1 window.
- *
- * NOTE: We do not set up I2O mapping.  I suspect that this is only
- * for an intelligent (target) device.  Using I2O disables most of
- * the mappings into PCI memory.
