vendorcode/amd/pi: Update AGESA_CFLAGS

* Split the existing cflags to a second line to stay under 80 characters
* Correctly identify the libagesa "Stage" by adding the __LIBAGESA__
define to the files when they're compiled.  This matches stage
defines such as __BOOTBLOCK__, __ROMSTAGE__, and __RAMSTAGE__. This is
needed to have printk actually show console information on whatever
interface the user has selected, such as the serial port, speaker,
SPI rom, or something else that hasn't been thought of yet.
