hikey, hikey960: Update kernel prebuilts for drm_hwcomposer

Update the 4.14 kernels only (for now) to enable use of the
drm_hwcomposer on the hikey and hikey960 platforms. This is a breaking
change and requires an updated userspace.

Includes the following changes:

20ebc74d51a1 hikey960_defconfig: Drop FBIOGET_DMABUF
d0455063e17c hikey/hikey960_defconfig: Remove FBDEV_EMULATION support for drm_hwcomposer
9815470ed175 drm/kirin960: don't turn on LDI at modeset
