Justin Chadwell 1578169edd Update meson platform to not rely on undefined overflow behaviour 
This consists of ensuring that the left operand of each shift is
unsigned when the operation might overflow into the sign bit.

Remi Pommarel b99f9224ed meson/gxl: Add support for SHA256 DMA engine 
In order to configure and boot SCP, BL31 has to compute and send
the SHA-256 of the firmware data via scpi. Luckily Amlogic GXL SOC
has a DMA facility that could be used to offload SHA-256
computations. This adds basic support of this hardware SHA-256
engine.
