rockchip: rk35xx: Fix boot with a large fdt blob

The TF-A blobs used to boot RK3568 and RK3588 boards is based on atf
v2.3. Mainline atf v2.3 contains an issue that could lead to a crash
when it fails to parse the fdt blob being passed as the platform param.
An issue that was fixed in atf v2.4.

The vendor TF-A seem to suffer from a similar issue, and this prevents
booting when fdt blob is large enough to trigger this condition.

Fix this by implying SPL_ATF_NO_PLATFORM_PARAM to let u-boot pass a
NULL pointer instead of the fdt blob as the platform param.

This fixes booting Radxa ROCK 3A after recent sync of device tree.
