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: add plumbing for updating interrupt endpoint
+ interval state
+
+xHCI caches device and endpoint data after the interface is configured,
+so an explicit command needs to be issued for any device driver wanting
+to alter the polling interval of an endpoint.
+
+Add usb_fixup_endpoint() to allow drivers to do this. The fixup must be
+called after calculating endpoint bandwidth requirements but before any
+URBs are submitted.
+
+If polling intervals are shortened, any bandwidth reservations are no
+longer valid but in practice polling intervals are only ever relaxed.
+
+Limit the scope to interrupt transfers for now.
