WIP: huawei-alice: new device (Huawei P8 Lite Ale-L21)

Adding new device port, but need help to get it booting.
I already asked in the nice matrix chat for help, but they got stuck too.

Maximum attention hook didn't help. Current console.ramoops output https://bin.disroot.org/?e8e6d285a6a22bf8#6nXeS4E7QGLx1dFdh2kVSsQFn1eWSt3Ye3pGypZoDKNs

Tried normal gcc, gcc6 and gcc4.
Tried both defconfigs found in the kernel repo.
RAM offsets are read from an booting img.
