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 commit '86588296acbf ("fdt: Properly handle "no-map"
field in the memory region")'.
Disabling it because Angler's firmware does not report where the memory
is allocated (dmesg from downstream kernel):
[ 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
Similar issue might be on Google Nexus 5X (lg-bullhead). Other MSM8992/4
are known to report correct address.
Fixes: 74d6d0a145835 ("arm64: dts: qcom: msm8994/8994-kitakami: Fix up the memory map")
