meta-phosphor: obmc-console: Add support for multiple ports

1. Add support to install multiple console port configuration files.
   OBMC_CONSOLE_TTYS is space separated list to set multiple ports.
   Defaults to OBMC_CONSOLE_HOST_TTY.

2. Prioritize picking up port specific configuration over generic one.

Tested:
Built for single and multi port configuration and verified the presence
of correct config file in sysconf directory.
