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] Initialise rpi-firmware before clk-bcm2835
+
+The IMA (Integrity Measurement Architecture) looks for a TPM (Trusted
+Platform Module) having been registered when it initialises; otherwise
+it assumes there is no TPM. It has been observed on BCM2835 that IMA
+is initialised before TPM, and that initialising the BCM2835 clock
+driver before the firmware driver has the effect of reversing this
+order.
+
+Change the firmware driver to initialise at core_initcall, delaying the
+BCM2835 clock driver to postcore_initcall.
+
+See: https://github.com/raspberrypi/linux/issues/3291
