brcm2708: rename target to bcm27xx

This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

+Subject: [PATCH] usb: dwc_otg: Use dma allocation for mphi dummy_send
+ buffer
+
+The FIQ driver used a kzalloc'ed buffer for dummy_send,
+passing a kernel virtual address to the hardware block.
+The buffer is only ever used for a dummy read, so it
+should be harmless, but there is the chance that it will
+cause exceptions.
+
+Use a dma allocation so that we have a genuine bus address,
+and read from that.
+Free the allocation when done for good measure.
