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] overlays: Correct gpio-fan gpio flags for 4.19
The gpio-fan overlay was submitted for the 4.14 kernel where the second
value in the Device Tree gpios declaration was ignored (thanks to an
old-style driver), allowing the fan-control output to be active-high
even though the declaration appears to request it be active-low.
The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
active-low flag that the overlay (accidentally?) supplies.
Change/correct the flags field to mark the GPIO as active-high.
