SPL_ATF_NO_PLATFORM_PARAM is selected by default for RK3399 configs, to

8109f738ffa7 "rockchip: increase FDT buffer size" in TF-A, passing a
device tree as platform parameter no longer causes problems for upstream
TF-A for RK3399.

Since SPL_ATF_NO_PLATFORM_PARAM doesn't need to be selected when using
upstream TF-A, change the Kconfig option from select to imply. It'll
still default to being selected but can be deselected by a user if they
know they will be using a compatible version of TF-A.

Thanks for this patch. Now with the latest TF-A and deselecting SPL_ATF_NO_PLATFORM_PARAM is it possible to get console output at the correct baudrate on TF.

For some background, see this thread on the TF-A list [1].

Since the corresponding required change isn't in a tagged version of
TF-A yet, and I don't know how many RK3399 boards are normally used with
older TF-A versions which required this option, I think it's safest to
keep the default as not sending a platform param to TF-A. Once the next
TF-A version is released, SPL_ATF_NO_PLATFORM_PARAM could be turned off
in defconfigs for boards that use the latest upstream TF-A.
