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. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de> Acked-by: Álvaro Fernández Rojas <noltari@gmail.com>

+Subject: [PATCH] w1: ds2482: cosmetic fixes after 54865314f5a1
+
+commit 5cb27d30fc3a281e830a2099d520b469e2b82008 upstream.
+
+We have a helper function ds2482_calculate_config() which is calculating
+the config value, so just use it instead of passing the same variable
+in all calls to this function.
+
+Also fixes the placement of module parameters to match with:
