Subject: [PATCH v2 0/3] Add initial support for T95 TV boxes

changes since v1:
- introduce sun50i-h616-t95.dtsi for common nodes in t95 boxes
- validate and add cd-gpios for microsd card detect
- add wi-fi node
- remove mmc2 node - it's not used
- add uart1 for bluetooth device
- update copyright

T95 is a most commonly known for being a box with a pre-installed 
malware. It uses Allwinner H616 and comes with NAND, and DDR3 
memory.

Those TV boxes usually come with common hardware:
- Allwinner H616 SoC
- 2/4 GB DDR3 SDRAM (Hynix H5TQ2G43BFR)
- 16/32/64 GB NAND flash
- microSD slot
- AXP305 or AXP313 PMIC depending on board revision
- 3.5mm A/V output
- HDMI port
- 2x USB 2.0 ports
- 100M ETH using Internal PHY
- LG642 Wi-Fi and BT chip (rebranded BCM43342)
- 7-segment display
- DC 5V barrel jack port

The board contains holes hor UART header wired to &uart0.
&uart1 is used by bluetooth module

>From the DRAM specification its operation voltage is 1.5V.
