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] usb: xhci: Raspberry Pi FW loader for VIA VL805
+
+The VL805 FW may either be loaded from an SPI EEPROM or alternatively
+loaded directly by the VideoCore firmware. A PCI reset will reset
+the VL805 XHCI controller on the Raspberry Pi4 requiring the firmware
+to be reloaded if an SPI EEPROM is not present.
+
+Use a VideoCore mailbox to trigger the loading of the VL805
+firmware (if necessary) after a PCI reset.
