[POWERPC] 8xx: mpc885ads pcmcia support
Adds support for PowerQuicc on-chip PCMCIA. The driver is implemented as of_device, so only arch/powerpc stuff is capable to use it, which now implies only mpc885ads reference board. To cope with the code that should be hooked inside driver, but is really board specific (like set_voltage), global structure mpc8xx_pcmcia_ops holds necessary function pointers that are filled in the BSP code.
