[OpenBIOS] [PATCH] drivers/escc.c: Add slot-names property ch-a node under escc

[Programmingkid]

Mac OS X's AppleSCCSerial kernel extension requires the slot-names property in order to use any serial ports. This patch adds the property.

After this patch is applied, the next thing that stops Mac OS X from using the serial port is something  having to do with DMA.

In this file the setPortName() function is what does the searching for slot-names.
