Subject: powerpc: Refactor board check for PCI quirks on FSL boards with
 uli1575

Refactor the check to determine if the quirk is applicable to the boards
into one inline function so we only have to change one place to add more
boards that the quirks might be applicable to.

Also removed a warning related to unused temp variable.

Subject: powerpc/85xx: Add P2020DS board support

The P2020 is a dual e500v2 core based SOC with:
* 3 PCIe controllers
* 2 General purpose DMA controllers
* 2 sRIO controllers
* 3 eTSECS
* USB 2.0
* SDHC
* SPI, I2C, DUART
* enhanced localbus
* and optional Security (P2020E) security w/XOR acceleration

The p2020 DS reference board is pretty similar to the existing MPC85xx
DS boards and has a ULI 1575 connected on one of the PCIe controllers.
