hikey960: Enable system power off callback

On Hikey960 if outputs GPIO176 low level, it can tell PMIC to power off
the whole board. To avoid resetting the board and stay off, it also
requires the SW2201's three switches 1/2/3 need to be all set to 0.

Since current code doesn't contain complete GPIO modules and misses to
support GPIO176. This patch adds all known GPIO modules and initialize
GPIO in BL31, and adds system power off callback to use GPIO176 for PMIC
power off operation.

Update hisilicon drivers 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.

Standardise header guards across codebase

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers
