boards: add roseapple pi board support

Add basic support for the roseapple pi board, a SBC in a RPI form factor
with an Actions Semiconductor S500 SoC. For details, see:

http://roseapplepi.org/

The vendor kernel unfortunately needs a minor patch to build the XHCI
driver, so include it here.

+[PATCH] unbreak xhci-trace compilation
+
+When commit 84a99f6fc5d4 (xhci: add traces for debug messages in
+xhci_address_device) was backported to the owl tree as part of commit
+5b2ea66f15396 (usb: add owl usb driver), the specific CFLAGS needed for
+xhci-trace.c were missed, causing build breakage:
+
+  CC      drivers/usb/host/xhci-trace.o
