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] bcm2835-mmc: Fix duplicate free_irq() on remove
+
+The BCM2835 MMC host driver requests its interrupt as a device-managed
+resource, so the interrupt is automatically freed after the driver is
+unbound.
+
+However on driver unbind, bcm2835_mmc_remove() frees the interrupt
+explicitly to avoid invocation of the interrupt handler after driver
+structures have been torn down.
+
+The interrupt is thus freed twice, leading to a WARN splat in
+__free_irq().  Fix by not requesting the interrupt as a device-managed
+resource.
