Adrian Schmutzler 7d7aa2fd92 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] Add overlay for SLB9760 Iridium /LetsTrust TPM
Device Tree overlay for the Infineon SLB9670 Trusted Platform Module add-on
boards, which can be used as a secure key storage and hwrng.
available as "Iridium SLB9670" by Infineon and "LetsTrust TPM" by
pi3g.
