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] nvmem: add type attribute
+
+commit 16688453661b6d5159be558a1f8c1f54463a420f upstream.
+
+Add a type attribute so userspace is able to know how the data is stored as
+this can help taking the correct decision when selecting which device to
+use. This will also help program display the proper warnings when burning
+fuses for example.
