BPi M2 Berry is a trimmed down version of the BPi M2 Ultra, completely
software compatible.

Changes include:
- 2GiB -> 1GiB
- no eMMC
- no onboard microphone
- no IR
- no blue LED
- no charging (and power jack to USB)
- dropped USB2 and connect USB1 to a 4-port HUB.

This patch brings the BPi M2 Berry to the same level as the BPi M2 Ultra
Includes the changes from:
commit c36fd5a48bd2 ("ARM: dts: sun8i: r40: bananapi-m2-ultra: Enable GMAC
ethernet controller")
commit db49c6825901 ("ARM: dts: sun8i: r40: Enable HDMI output on BananaPi
M2 Ultra")
commit ccefd95f648a ("ARM: dts: sun8i: r40: Add missing TCON-TOP - TCON
connections")
commit 6a7556f604f9 ("ARM: dts: sun8i: r40: Disable TCONs by default.")
commit 666907a3f9bd ("ARM: dts: sun8i: sun8i-r40-bananapi-m2-ultra: enable
AHCI")
commit e5c6e693be83 ("ARM: dts: sun8i: r40: bananapi-m2-ultra: Fix WiFi
regulator definitions")
commit 1e5f1db4ccd8 ("ARM: dts: sun8i: r40: bananapi-m2-ultra: Add
Bluetooth device node")
