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] dtoverlays: Add an overlay for the Infineon IRS1125
+
+The Infineon IRS1125 is a CSI2 time of flight depth sensor
+which has a suitable V4L2 subdevice driver.
+
+Add an overlay for configuring it.

++Name:   irs1125
++Info:   Infineon irs1125 TOF camera module.
++        Uses Unicam 1, which is the standard camera connector on most Pi
++        variants.
++Load:   dtoverlay=irs1125,<param>=<val>
++Params: i2c_pins_0_1            Use pins 0&1 for the I2C instead of 44&45.
++                                Useful on Compute Modules.
++
++        i2c_pins_28_29          Use pins 28&29 for the I2C instead of 44&45.
++                                This is required for Pi B+, 2, 0, and 0W.

+ Name:   jedec-spi-nor
+ Info:   Adds support for JEDEC-compliant SPI NOR flash devices.  (Note: The
