Andres Salomon 73d2eaac8a CS5536: apply pci quirk for BIOS SMBUS bug
The new cs5535-* drivers use PCI header config info rather than MSRs to
determine the memory region to use for things like GPIOs and MFGPTs.  As
anticipated, we've run into a buggy BIOS:

[    0.081818] pci 0000:00:14.0: reg 10: [io  0x6000-0x7fff]
[    0.081906] pci 0000:00:14.0: reg 14: [io  0x6100-0x61ff]
[    0.082015] pci 0000:00:14.0: reg 18: [io  0x6200-0x63ff]
[    0.082917] pci 0000:00:14.2: reg 20: [io  0xe000-0xe00f]
[    0.083551] pci 0000:00:15.0: reg 10: [mem 0xa0010000-0xa0010fff]
[    0.084436] pci 0000:00:15.1: reg 10: [mem 0xa0011000-0xa0011fff]
[    0.088816] PCI: pci_cache_line_size set to 32 bytes
[    0.088938] pci 0000:00:14.0: address space collision: [io 0x6100-0x61ff] already in use
[    0.089052] pci 0000:00:14.0: can't reserve [io  0x6100-0x61ff]

This is a Soekris board, and its BIOS sets the size of the PCI ISA bridge
device's BAR0 to 8k.  In reality, it should be 8 bytes (BAR0 is used for
SMBus stuff).  This quirk checks for an incorrect size, and resets it
accordingly.
