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] bcm2708_fb: Fix layout of struct
+ vc4_display_settings_t
+
+The display parameters returned by the VC4 firmware in response to the
+RPI_FIRMWARE_FRAMEBUFFER_GET_DISPLAY_SETTINGS tag do not match the
+layout of struct vc4_display_settings_t: the colour depth and row
+pitch are erroneously swapped in the kernel definition.  This can
+trigger a kernel warning from pixel_to_pat(), such as:
+
+  pixel_to_pat(): unsupported pixelformat 7296
+
+Fix by adjusting the layout of struct vc4_display_settings_t to match
+the layout as used by the VC4 firmware.
