payloads/iPXE: add iPXE serial enable option 

Since SeaBIOS 1.11.0 implements serial console and etc/sercon-port
runtime config file is present in CBFS, SeaBIOS additionally
redirects iPXE output to configured IO port. For boards which use
the same UART for SeaBIOS and iPXE console it causes doubled
output.

The option is enabled by default and passes UART configuration
to iPXE Makefile as before. When unselected, only SeaBIOS handles
printing output from iPXE.

Enable/disable iPXE serial console. Since SeaBIOS supports serial
console this option might be helpful to avoid duplicated output.
