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] drm/vc4: Correct handling of rotation parameter in
fkms
One bit within DRM_MODE_ROTATE_MASK will always be set to
determine the base rotation 0/90/180/270, and then REFLECT_X
and REFLECT_Y are on top.
Correct the handling which was assuming that REFLECT_[X|Y]
was instead of ROTATE_x.
