device-odroid-hc2: switch to linux-edge (MR 3378)

ODROID HC2 is based upon the Samsung Exynos 5422 and can run full
mainline. Switch to linux-edge from Alpine to enable this and drop
the close-to-mainline fork for this device. The close-to-mainline
fork was already linux-edge for a while but with a separate KConfig.
These KConfig changes are now integrated in linux-edge of Alpine.

U-boot script was updated to handle vmlinuz-edge as well since
Alpine's linux-edge does not generate a vmlinuz file, but vmlinuz-edge.
Probably to allow installing linux-lts as well.

initcall_blacklist=exynos_drm_init was added to the kernel cmdline
because upstream wants to set CONFIG_DRM_EXYNOS=y instead of module.
The DRM subsystem of Exynos5 in the kernel seems to be broken for this
device. There's also no use for it since this device does not have video
out. See https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/38094
