Guodong Xu 8f5203abdc arm64: dts: hikey: extend default cma size to 128MB 
To support display in Debian on HiKey, cma heap is used to allocate
graphic buffers. The default size of CMA is 16 MB which is not enough.

Increase the default CMA size to 128 MB.

*
* When the 96Board naming of a line and the schematic name of
* the same line are in conflict, the 96Board specification
* takes precedence, which means that the external UART on the
* LSEC is named UART0 while the schematic and SoC names this
* UART2. This is only for the informational lines i.e. "[FOO]",
* the GPIO named lines "GPIO-A" thru "GPIO-L" are the only
* ones actually used for GPIO.
