Subject: rapidio: modify configuration to support PCI-SRIO controller
From: Alexandre Bounine <alexandre.bounine@xxxxxxx>
1. Add an option to include RapidIO support if the PCI is available.
2. Add FSL_RIO configuration option to enable controller selection.
3. Add RapidIO support option into x86 and MIPS architectures.
