As the default definition breaks booting angler:
[ 1.862561] printk: console [ttyMSM0] enabled
[ 1.872260] msm_serial: driver initialized
D - 15524 - pm_driver_init, Delta
cont_splash_mem was introduced in 74d6d0a145835, but the problem
manifested after 86588296acbf ("fdt: Properly handle "no-map" field
in the memory region").
Disabling it because downstream kernel does not report where the memory
is allocated:
[ 0.000000] cma: Found cont_splash_mem@0, memory base 0x0000000000000000, size 16 MiB, limit 0x0000000000000000
[ 0.000000] cma: CMA: reserved 16 MiB at 0x0000000000000000 for cont_splash_mem
Fixes: 74d6d0a145835 ("arm64: dts: qcom: msm8994/8994-kitakami: Fix up
the memory map")

Changes v2->v3:
* get back to v1 which just disabled the node
* use alias instead of memory@3800000
