eglfs: Introduce hooks for the eglfs plugin
EGL provides an api to create a rendering context for khronos APIs
on native surfaces. The board initialization and window creation
is platform specific.
This commit adds platform hooks/extensions to the EGLFS plugin and
implements them for the Amlogic 8726M. The hook interface is internal
and there are no ABI/API guarantees.
EGLFS is now linked with -Wl,-no-undefined to make sure that a hook does not
add unresolvable symbols.
