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] media: ov5647: Use gpiod_set_value_cansleep
+
+All calls to the gpio library are in contexts that can sleep,
+therefore there is no issue with having those GPIOs controlled
+by controllers which require sleeping (eg I2C GPIO expanders).
+
+Switch to using gpiod_set_value_cansleep instead of gpiod_set_value
+to avoid triggering the warning in gpiolib should the GPIO
+controller need to sleep.
