board/raspberrypi*: remove dtparam krnbt=on
...
The config.txt of the Rasperry Pi's supporting Wi-Fi and Bluetooth (i.e.
zero W, zero 2 W, 3, and 4) switch the Bluetooth function to use the
mini-UART (ttyS0) and restore UART0 (ttyAMA0) over the GPIOs 14 and 15
(as per miniuart-bt-overlay.dts[1]). All of them turn "on" the parameter
krnbt to autoprobe the bluetooth driver.
According to the README.md, the dtparam krnbt is now defaulting to "on"
since linux-raspberrypi 6.1.y[2]; it was defaulting to "off" before[3].
This removes the dtparam=krnbt=on from these config.txt files since the
value set is actually the default value.

board/raspberrypi: reword console comment
...
The Raspberry Pi with Bluetooth connectivity up to 4 (i.e. Zero W, Zero
2 W, 3, 4 and Compute Module 4) use the miniuart-bt overlay to restore
UART0 for the serial console (like the Raspberry Pi and Raspberry Pi 2
that have no Bluetooth); the Bluetooth uses the mini-UART instead[1][2].
This rewords the comment instead of enumerating every hardwares that can
be extended in the future.

board/raspberrypi: add Raspberry Pi Zero 2 W
...
The Raspberry-Pi Zero 2 W is an affordable single board computer. It is
a more powerful drop-in replacement for the Raspberry Pi Zero W.
The board incorporates an Raspberry-Pi RP3A0 system-in-package (SiP) with
a Broadcom BCM2710A1 and 512MB LPDDR2 SDRAM. The CPU is a quad-core 1Ghz
64-bit Arm Cortex-A53. As for other Raspberry-Pis it also provides
2.4GHz 802.11 b/g/n Wifi, Bluetooth 4.2 and BLE.
The BCM2710 cpu is similar to the Raspberry-Pi 3, it uses the same
kernel configuration as the Raspberry-Pi 2 and 3.
