Do not require PCI code for RayeR SPI driver

Browse Source 
CONFIG_RAYER_SPI only needs raw hardware access, but not libpci.
Disable CONFIG_RAYER_SPI on Android because of missing inb/outb.
Introduce NEED_RAW_ACCESS for raw memory access, PCI port I/O
and MSR access.

Corresponding to flashrom svn r1934.
